ANALYSIS OF THE ELASTO-PLASTIC PROPERTIES AND COMPUTATIONAL MODELS FOR TWO-PHASE COMPOSITES
两相材料的弹塑性性质和计算模型分析

A three region model was proposed to study elasto-plastic mechanical behavior of two-phase composites by finite deformation FEM. The influences of two region model,three region model and periodic distribution particle model on the calculated results were compared. The effects of shape, distribution and volume fraction of inclusions on the elasto-plastic mechanical behavior were analyzed. The results obtained in this paper are important for understanding macro-behavior of two phase composites.
