基于物质点方法饱和多孔介质动力学模拟(Ⅱ)——饱和多孔介质与固体间动力接触分析
Material point method for dynamic analysis of saturated porous media (Ⅱ): dynamic contact analysis between saturated porous media and solid bodies
摘要
Abstract
The strategy for the dynamic contact between saturated porous media and solid bodies is proposed in the frame work of material point method (MPM), where the dynamic responses of saturated porous media and solid bodies are respectively simulated using the coupling MPM and the original MPM. The link between the two kinds of MPMs is the contact algorithm proposed in the current research, in which the slip between saturated porous media and solid bodies is allowed with the assumption that the penetration between saturated porous media and solid bodies is forbidden and follows the Coulomb friction law. The results of numerical calculations demonstrate the validity of the proposed strategy which shines a light of modeling the problems of soil-structure interaction in a new and effective way.关键词
