| Outline of Final Research Achievements |
We focus on dynamic behavior of intermediate state of solid and fluid materials. Liquefied ground is one of the typical examples. In order to simulate the behavior accurately, common governing equations are introduced representing both solid and fluid materials, and develop a numerical scheme in Lagrange coordinate system. The developed code is verified by static and dynamic analysis on the material combining linear elastic material and Newton fluid. We apply the codes to saturated sand, and analyze the liquefaction considering the sloshing behavior. Results show liquefaction induced by vertical vibration of free surface.
