Particle reinforced metal matrix composite (PRMMCs) has a complex mesoscopic structure, and the addition of particles can strengthen the metal matrix, which makes the deformation and failure behavior of PRMMCs under load very complicated. The finite element method can quantitatively describe the effect of PRMMCs microstructure parameters on the macroscopic properties of materials, but the key is to establish a representative volume element(RVE) model that can reflect the real mechanical properties of materials. This paper reports and discusses on the construction methods of the RVE model of PRMMCs from three aspects: the geometric modeling of PRMMCs microstructure, the construction of the matrix constitutive equation based on PRMMCs reinforcement mechanism and the interface module. In the end, Abaqus and some of its secondary development functions are introduced.
颗粒增强金属基复合材料(PRMMCs)具有复杂的细观结构,颗粒的加入强化了金属基体,这使得PRMMCs在载荷作用下的变形和失效行为非常复杂。有限元方法能够定量描述PRMMCs微观结构参数对材料宏观性能的影响,关键在于建立能够反映材料真实力学性能的代表性体积单元(RVE)模型。本文从PRMMCs微观结构的几何建模、基于PRMMCs增强机制的基体本构方程构建以及界面模块三个方面报道并讨论了PRMMCs的RVE模型构建方法。最后,介绍了Abaqus及其一些二次开发功能。
