  • Stress Development Up To Crack Formation in Drying Paste

    So Kitsunezaki; Yousuke Matsuo; Akio Nakahara

    We investigate the development of stresses in a drying process of paste-like materials theoretically and experimentally. An invasion percolation model on a nonlinear elastic lattice can describe cracking processes resulting from drying contraction as well as dry processes in the bulk of the system and gives a non-dimensional parameter to determine the conditions at which cracking precedes drying. This model also predicts that horizontal tensions increase isotropically with drying. However, paste often exhibits anisotropic crack formation due to plasticity, as is known as the memory effect. We measured stresses in a drying process of calcium carbonate (CaCO3) paste and confirmed that anisotropy in residual stress increases with uniform drying until crack formation when shaking is applied to a paste layer for a short time initially., SOC CHEMICAL ENG JAPAN, Oct. 2017, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 50 (10), 775 - 779, doi;web_of_science

  • Memory effect and anisotropy of particle arrangements in granular paste

    So Kitsunezaki; Arina Sasaki; Akihiro Nishimoto; Tsuyoshi Mizuguchi; Yousuke Matsuo; Akio Nakahara

    It is known that pastes of fine powder, for example those of clay, retain memory of shaking applied early in a drying process. This memory results in the appearance of anisotropic patterns of desiccation cracks after drying. In this work, we find a similar behavior in pastes consisting of large granular particles, specifically cornstarch and Lycopodium spores. Because of the large particle size, we were able to observe particle arrangements in Lycopodium paste with micro-focus X-ray computerized tomography (mu CT). We prepared pastes consisting of Lycopodium particles and water. Agar was added to the paste in order to allow for solidification during a drying process. In these samples, we found statistical anisotropy induced by shaking applied early in the drying process. This anisotropy possesses a feature that was predicted on the basis of results obtained in previous experimental and theoretical studies., SPRINGER, Oct. 2017, EUROPEAN PHYSICAL JOURNAL E, 40 (10), 88, doi;web_of_science

  • Effect of disorder on shrinkage-induced fragmentation of a thin brittle layer

    Zoltan Halasz; Akio Nakahara; So Kitsunezaki; Ferenc Kun

    We investigate the effect of the amount of disorder on the shrinkage-induced cracking of a thin brittle layer attached to a substrate. Based on a discrete element model we study how the dynamics of cracking and the size of fragments evolve when the amount of disorder is varied. In the model a thin layer is discretized on a random lattice of Voronoi polygons attached to a substrate. Two sources of disorder are considered: structural disorder captured by the local variation of the stiffness and strength disorder represented by the random strength of cohesive elements between polygons. Increasing the amount of strength disorder, our calculations reveal a transition from a cellular crack pattern, generated by the sequential branching and merging of cracks, to a disordered ensemble of cracks where the merging of randomly nucleated microcracks dominate. In the limit of low disorder, the statistics of fragment size is described by a log-normal distribution; however, in the limit of high disorder, a power-law distribution is obtained., AMER PHYSICAL SOC, Sep. 2017, PHYSICAL REVIEW E, 96 (3), 033006, doi;web_of_science

  • Shaking-induced stress anisotropy in the memory effect of paste

    So Kitsunezaki; Akio Nakahara; Yousuke Matsuo

    When paste of fine granular particles and water is shaken in one direction and then left undisturbed, memory of the direction of shaking is retained for a sufficiently long time to result in a directional crack pattern that appears after drying. Although it has been conjectured that anisotropy in residual stresses caused by plastic deformation is responsible for this memory effect, to this time, no evidence of such anisotropy has been found. We experimentally investigated the stress in drying paste by measuring the bending of elastic plates supporting the paste sample and found stress anisotropy developing in paste. Additional bending tests suggested that paste retains plasticity during the drying process and that plastic deformation is not always frozen in place after initial shaking.

  • Cracking condition of cohesionless porous materials in drying processes

    So Kitsunezaki

    The invasion of air into porous systems in drying processes is often localized in soft materials, such as colloidal suspensions and granular pastes, and it typically develops in the form of cracks before ordinary drying begins. To investigate such processes, we construct an invasion percolation model on a deformable lattice for cohesionless elastic systems, and with this model we derive the condition under which cracking occurs. A Griffith-like condition characterized by a dimensionless parameter is proposed, and its validity is checked numerically. This condition indicates that the ease with which cracking occurs increases as the particles composing the material become smaller, as the rigidity of the system increases and as the degree of heterogeneity characterizing the drying processes decreases. © 2013 American Physical Society., 17 May 2013, Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 87 (5), 052805, doi;pubmed

  • Crack growth in drying paste

    So Kitsunezaki

    The main features of crack patterns in drying paste have been explained by assuming that the paste is an elastic material when cracking occurs. However, recent studies have revealed that the porous and rheological properties of the paste influence the fracture processes. Starting from a spring-network model for a thin layer of paste, the memory effect found by Nakahara and directional crack growth are reviewed. We measured crack speeds in a uniformly dried thin layer of paste and found that crack growth depended significantly on the drying rate. Such dependence suggests that crack growth competes with plastic relaxation in paste. (c) 2011 The Society of Powder Technology Japan.

  • Crack Growth and Plastic Relaxation in a Drying Paste Layer

    So Kitsunezaki

    Uniform drying causes a quasi-two-dimensional cellular crack pattern in a thin layer of paste. In our previous research, we found that such cracks are created in a capillary state, and that the growth speed is determined by the rate of increase in tension in the layer, rather than by the magnitude of the tension itself. In this paper, we present a theoretical investigation of the effects of increasing negative pore pressure and plastic deformation on crack growth using a modified spring network model. The analytical and numerical results indicate that the stress-rate dependence of crack speed could be caused by the competition between plastic relaxation and crack growth., PHYSICAL SOC JAPAN, Dec. 2010, JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN, 79 (12), 124802, doi;web_of_science

  • Crack Propagation Speed in the Drying Process of Paste

    So Kitsunezaki

    We investigated crack propagation in the drying process of a thin layer of calcium carbonate (CaCO3) paste experimentally. Cracks are induced by uniform desiccation from the top surface of it layer at the approximately same water content for various drying conditions. We found that the crack speed is it nonlinear increasing function of the drying rate at the cracking time although the tensile stresses arising in the bulk of paste do not depend practically on the drying rate. The crack speed does not depend significantly on the layer thickness and decreases in the cases in which glycerol is mixed to increase the viscosity of paste. These results suggest that dynamical crack growth occurs with viscoplastic relaxation in the vicinity of crack tips., PHYSICAL SOC JAPAN, Jun. 2009, JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN, 78 (6), 064801, doi;web_of_science

  • Bioconvection and front formation of Paramecium tetraurelia

    So Kitsunezaki; Rie Komori; Terue Harumoto

    We have investigated the bioconvection of Paramecium tetraurelia in high-density suspensions made by centrifugal concentration. When a suspension is kept at rest in a Hele-Shaw cell, a crowded front of paramecia is formed in the vicinity of the bottom and it propagates gradually toward the water-air interface. Fluid convection occurs under this front, and it is driven persistently by the upward swimming of paramecia. The roll structures of the bioconvection become turbulent with an increase in the depth of the suspension; they also change rapidly as the density of paramecia increases. Our experimental results suggest that lack of oxygen in the suspension causes the active individual motions of paramecia to induce the formation of this front., AMER PHYSICAL SOC, Oct. 2007, PHYSICAL REVIEW E, 76 (4), 046301, doi;web_of_science

  • Numerical study of drying process and columnar fracture process in granule-water mixtures

    Akihiro Nishimoto; Tsuyoshi Mizuguchi; So Kitsunezaki

    The formation of three-dimensional prismatic cracks in the drying process of starch-water mixtures is investigated numerically. We assume that the mixture is an elastic porous medium which possesses a stress field and a water content field. The evolution of both fields is represented by a spring network and a phenomenological model with the water potential, respectively. We find that the water content distribution has a propagating front which is not explained by a simple diffusion process. The prismatic structure of cracks driven by the water content field is observed. The depth dependence and the coarsening process of the columnar structure are also studied. The particle diameter dependence of the scale of the columns and the effect of the crack networks on the dynamics of the water content field are also discussed., AMER PHYSICAL SOC, Jul. 2007, PHYSICAL REVIEW E, 76 (1), 016102, doi;web_of_science

  • Spatio-temporal patterns of bacteria caused by collective motion

    S Kitsunezaki

    In incubation experiments on bacterial colonies of Proteus mirabilis, collective motion of bacteria is found to generate macroscopic turbulent patterns on the surface of agar media. We propose a mathematical model to describe the time evolution of the positional and directional distributions of motile bacteria in such systems, and investigate this model both numerically and analytically. It is shown that as the average density of bacteria increases, nonuniform swarming patterns emerge from a uniform stationary state. For a sufficient large density, we find that spiral patterns are caused by interactions between the local bacteria densities and the rotational mode of the collective motion. Unidirectional spiral patterns similar to those observed in experiments appear in the case in which the equilibrium directional distribution is asymmetric.

  • Directional crack propagation of granular water systems

    T Mizuguchi; A Nishimoto; S Kitsunezaki; Y Yamazaki; Aoki, I

    Pattern dynamics of directional crack propagation phenomena observed in drying process of starch-water mixture is investigated. To visualize the three-dimensional structure of the drying-fracture process two kinds of experiments are performed, i.e., resin solidification planing method and real-time measurement of water content distribution with MR instruments. A cross section with polygonal structure is visualized in both experiments. The depth dependency of cell size is measured. The phenomenological model for water transportation is also discussed., AMER PHYSICAL SOC, May 2005, PHYSICAL REVIEW E, 71 (5), 056122, doi;web_of_science

  • Quasi-static deformation of a granular system with a regular arrangement of particles

    S Kitsunezaki

    In order to study the growth of heterogeneity in granular systems, we investigate the quasi-static deformation of monodisperse particle systems with regular initial arrangements. We construct a linearized model by limiting our consideration to infinitesimal deformations. Assuming Coulomb friction, we introduce new variables to express the slippage distances of particles in contact. The results of our numerical simulations show that heterogeneities appear through a fingering-like instability and develop into several microscopic shear zones. The equations in our model can be reduced to simpler equations in the limit of small tangential interactions using a perturbative analysis. In the long wavelength limit, the equations are analogous to models of Laplacian growth, such as the fuse problem. We investigate the instability of critical stress states and the competitive growth of microscopic shear zones., SPRINGER, Dec. 2004, GRANULAR MATTER, 6 (4), 221 - 228, doi;web_of_science

  • Dynamic scaling of the growing rough surfaces

    N Kobayashi; O Moriyama; S Kitsunezaki; Y Yamazaki; M Matsushita

    We have numerically investigated the self-affinity of the bacterial colony model. In order to examine the growth exponent beta, we find a new approach to the dynamic scaling hypothesis for the growing rough surface. We have first investigated the self-affinity of the well-known Eden model to check the validity of the new approach. The obtained results of the exponents alpha congruent to 0.50 and beta congruent to 0.33 coincide with the wellknown values of the exponents of the Eden model. We have then applied it successfully to growing interfaces produced by the bacterial colony model. We have found that the self-affinity of the bacterial colony model is characterized as alpha congruent to 0.80 and beta congruent to 0.65., PHYSICAL SOC JAPAN, Aug. 2004, JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN, 73 (8), 2112 - 2116, doi;web_of_science

  • The Creation Process of Faults in Quasi-static Deformation

    S. Kitsunezaki; A. Kurumatani

    We investigated quasi-static deformation processes of granular systems both by experiments and numerical calculations. We simulated the deformation of a regular arrangement of particles using the discrete elements method and found that the initial deformation of the granular system causes the formation of microscopic shear zones through a fingering-like instability of the stress field. These microscopic shear zones propagate as their localized strain increases in magnitude and then evolves into macroscopic faults. The picture of a fingering-like instability is consistent with our experimental results concerning the creation sequence and spacing of faults appearing in a granular system contained in a V-shaped container., Feb. 2004, Granular Matter, 5 (4), 185 - 192, doi

  • Fracture patterns induced by desiccation in a thin layer

    S Kitsunezaki

    We study a theoretical model of mud cracks, that is, the fracture patterns resulting from the contraction with drying in a thin layer of a mixture of granules and water. In this model, we consider the slip on the bottom of this layer and the relaxation of the elastic field that represents deformation of the layer. Analysis of the one-dimensional model gives results for the crack size that are consistent with experiments. We propose an analytical method of estimation for the growth velocity of a simple straight crack to explain the very slow propagation observed in actual experiments. Numerical simulations reveal the dependence of qualitative nature of the formation of crack patterns on material properties.

  • Interface dynamics for bacterial colony formation

    S Kitsunezaki

    We propose a differential-equation model with a nonlinear diffusion term for explaining pattern formation of bacterial colonies, and carry out its numerical simulations. Our model is reduced to an interface dynamics by means of a systematic perturbation method. This is similar to a model system for viscous fingering except that the field around an interface obeys a diffusion equation and that surface tension does not work on the interface. How the difference in morphology results depending on the condition is explained qualitatively., PHYSICAL SOC JAPAN, May 1997, JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN, 66 (5), 1544 - 1550, doi;web_of_science

  • Modeling for fingering patterns with an assembly of splitting elements

  • Spatio-temporal patterns in colonies of rod-shaped bacteria

    S Kitsunezaki

    In incubation experiments of bacterial colonies of Proteus Mirabilis, macroscopic spatiotemporal patterns, such as turbulent and unidirectional spiral patterns, appear in colonies. Considering only kinetic propeties of rod-shaped bacteria, we propose a phenomenological model for the directional and positional distributions. As the average density increases, homogeneous states bifurcate sub-critically into nonuniform states exhibiting localized collective motion, and spiral patterns appear for sufficiently large density. These patterns result from interactions between the local bacteria densities and the order parameter representing collective motion. Our model can be described by reduced equations using a perturbative method for large density. The unidirectionality of sprial rotation is also discussed., PROGRESS THEORETICAL PHYSICS PUBLICATION OFFICE, 2006, PROGRESS OF THEORETICAL PHYSICS SUPPLEMENT, 161 (161), 224 - 227, doi;web_of_science

With some combination of granular material and liquid, nonuniform shrinkage induced by drying process causes crack formation of bulk sample in several ways. Especially, directional crack propagation and columnar structure formation are observed in the experiments.

    We report experimental results for a system in which stripe patterns appear on the surface of granular matter. These stripes are induced by the slow deformation of the container.
