| Research Abstract |
In this study, I developed a multi-scale numerical method for the deformation of grains-water coupling system based on a nonlinear homogenization method. Moreover, we carried out the numerical simulation of the grain-water coupling problems to investigate the strength and deformation characteristics. At first, a governing equation of the grains-water coupling deformation problems in the saturated state was formulated. Next, I developed the original simulation program for the problems. At the same time, I carried out the experiment and visualization of the deformation behavior of grains-liquid coupling systems to grasp micro-mechanical phenomena. As the results in this study, I was able to simulate the mechanical behavior of the saturated grains-water system.
