摘要:: 越来越多的研究发现增强体空间构型分布有望成为金属基复合材料强韧性倒置问题的有效解决办法。然而，构型设计要素种类繁多，除传统结构设计要素外，还包括增强体分布特征等结构参数。因此，仅靠传统的实验手段已无法满足复合材料构型设计的研究需求，借助有限元模拟探索各构型要素对复合材料性能的影响规律可作为试验研究的前提和有效补充。基于三维几何模型的有限元模拟技术，将增强体分布特征引入复合材料三维几何模型中，再引入各组分的物理及力学性能，则能够对构型化复合材料的变形与断裂行为进行模拟，并预测其力学性能。首先回顾了数值模拟颗粒增强金属基复合材料的几何和数值模型构建方法，然后对网状结构构型化复合材料有限元模拟工作的研究现状进行了介绍，最后对构型化复合材料有限元模拟工作的未来发展进行了展望。

Abstract:: Recently, it was proved that tailoring the reinforcement distribution is expected to overcome the contradiction between the strength and toughness of metal matrix composites (MMCs). However, the architectural design includes many factors, i.e. reinforcement size, shape and types as well as structural parameters. Thus, traditional experimental methods can’t meet the research demand of architectural design, and consequently, investigating the effect of structural factors on the properties of the composites via finite element method (FEM) becomes a necessity. Through building three-dimensional geometric models and introduing constitutive laws of matrix, reforcement and interface, one can predict deformation/failure behaviors and mechanical properties of composites with a range of tailored architectures. In this paper, the modeling process of particle reinforced MMCs was firstly reviewed. Then the research progress of FEM simulation on composites with network architectures was presented following by an outlook to the future of FEM simulation on composite with various architectures.
