论文摘要
在本文中，我们研究了异质地材料中弹性塑性的一些微机械方面。目的是为代表性的材料的代表性体积提高弹性行为，这确实是一项非常具有挑战性的任务，这是由于所涉及的不可逆变形。考虑到塑料应变是特征菌株，使我们能够采用连续微力学提供的强大工具，这些工具主要是为了对特征压力的弹性媒体进行扫描。在本文中，通过将其预测与有限元（FE）模拟进行比较，在此检查了这种基于本本元的弹性塑性性的有效性。
In this paper, we investigate some micromechanical aspects of elasto-plasticity in heterogeneous geomaterials. The aim is to upscale the elasto-plastic behavior for a representative volume of the material which is indeed a very challenging task due to the irreversible deformations involved. Considering the plastic strains as eigen-strains allows us to employ the powerful tools offered by Continuum Micromechanics which are mainly developed for upscaling of eigen-stressed elastic media. The validity of such eigen-strain based formulation of multiscale elasto-plasticity is herein examined by comparing its predictions against Finite Element (FE) simulations.
