HOMOGENISATION METHOD FOR THE ANALYSIS OF ASSEMBLAGE OF ELASTIC CONTACT GRAINS, Part Ⅱ: MACRO HOMOGENISATION ANALYSIS

  • 摘要: 基于文献1的工作,给出弹性接触颗粒状组成周期性结构材料宏观力学均匀化分析新方法。该方法的特点是在对材料进行微观分析的基础上建立宏观材料的均匀化非线性数值本构模型,并在此基础上构造宏观分析的一致性方法。给出了数值算例,说明了方法的正确性与有效性。

     

    Abstract: Based on the work presented in paper 1, a new homogenisation method for the analysis of assemblage of elastic contact bodies is proposed in this paper. An important feature of this work is to define numerically a homogenised constitutive relationship for the global behaviour of the assemblies in terms of the analysis on the RVE level, and a new consistent homogenisation method is furthermore presented. Numerical example and results are given to demonstrate the validity and efficiency of the new method.
