摘要
基于细观模型，提出了一种简单的分析颗粒增强金属基复合材料塑性变形响应的唯象模型。运用该模型可以很方便地预测不同颗粒体积含量复合材料的弹性模量、屈服应力、应力－应变塑性响应等。实验模型分析表明，增强颗粒自身破裂和颗粒与基体界面破裂是该类材料破坏的两个主要机制。
Based on the microstructure, a simple phenomenal model for the plastic response of particle reinforced composites is built. It is relatively simple to predict the elastic modulus, yield stress and stress-strain response of the composites with different volume fraction of particles by the model. The experimental results confirm that the fracture of the reinforcing particles and debounding of the particles and matrix are the two main mechanisms of the composite rupture.
