研究工作目的是建立弹性接触颗粒状组成周期性结构材料力学分析的均匀化模型。首先对具有周期性构造的弹性接触颗粒材料力学的微观 (小尺度 )与宏观两级均匀化方法的研究现状进行了简要回顾 ,进而发展了问题局部 RVE分析的有限元求解技术 ,该方法考虑了弹性接触体的粘着界面特性 ,并基于参变量变分原理提出了问题求解的参数二次规划算法 ,为宏观均匀化分析工作打下基础 The purpose of this study is to establish a homogenization model for the mechanical analysis of material with a periodic structure that is elastically in contact with the particles. First of all, a brief review is made on the mechanics of microscopic (small scale) and macroscopic two-level homogenization methods for elastic contact granular materials with periodic structure. Then the finite element method for local RVE analysis of the problem is developed. The method considers Elastic contact body adhesion interface characteristics, and based on the parametric variational principle to solve the parameter quadratic programming algorithm to lay the foundation for the analysis of the macroscopic homogenization
