2019 個別要素法を用いた含水土壌のモデル化(S04-3 FEM/メッシュフリー法/粒子法とその関連技術(3),S04 FEM/メッシュフリー法/粒子法とその関連技術)
詳細
The Distinct Element Method (DEM) has been applied for the analysis of dynamic interactions between soil and vehicle. The DEM makes it possible to analyze the discrete behavior of soil. However, the cohesive property of soil should be considered additionally because the cohesion influences the soil behavior largely. In this study, the adhesive force caused by liquid bridge was applied to the DEM, and the wet soil model was constructed. To investigate the validity of the wet soil model, we conducted the simulation of bar penetration. The result of simulation is corresponding to the similar experiment in the soil deformation.
