| 摘 要： | 针对目前常规数值计算方法的局限,该文采用一种纯拉格朗日、无网格方法-光滑粒子流体动力学法(简称SPH法)对土体的大变形力学行为进行数值模拟.首先,根据SPH法的基本理论,对弹塑性力学控制方程进行了离散,构造了应力-应变关系的SPH求解格式,并采用Jaumann应力率进行土体应力.应变与内部质点运动间的转换.然后,进行两...

| Abstract: | In order to overcome limitations of normal calculation methods,a meshless,Lagrangian particle method,namely Smoothed Particle Hydrodynamics(SPH) is applied to simulate the process of soil large deformation.Firstly,based on the theory of SPH,the formulations on elastoplastic mechanical governing equations are discreted.Meanwhile,the corresponding stress-strain relationship in SPH program is proposed and the transformation between stress-strain relationship and the movement of internal particles in soil is co... |
