中文摘要: 基于不动点迭代理论提出了一种根据复合材料微观结构分析宏观力学性能的数值方法.将该方法与有限元分析相结合,对TiC颗粒增强钛基复合材料的弹塑性拉伸行为进行了数值模拟,研究了颗粒形状和颗粒大小的变化对复合材料宏观力学性能的影响.结果显示,颗粒形状对复合材料力学性能的影响不大;随着颗粒大小的增加,复合材料的弹性模量、屈服强度和强化模量等均明显提高.
Abstract:Based on the fixed point iteration theory,a numerical method for macroscopic mechanical behavior of composites according to microstructures was proposed.Combining it with FEM,numerical simulations of the elastic-plastic tensile properties of TiC particle reinforced titanium matrix composites were carried out.The effect of particle shape and particle size on the macroscopic mechanical properties of composites was investigated.The results show that the influence of particle shape on mechanical properties of c...
