摘要: 为考查通用单胞模型和弱界面分离模型模拟复合材料界面脱黏的有效性,考虑了柔性界面,常响应界面和渐进适应界面三种不同的界面分离模型,并分析了界面对材料性能的影响.计算结果表明,将界面分离模型集成到通用单胞模型中,增强了通用单胞模型的适用范围和对复合材料力学响应特性的模拟分析能力.Abstract: In order to validate the ability of the generalized method of cell(GMC) with weak interface in modeling the interface debonding within continuum fiber reinforced composite,three kinds of week interface were considered in this paper to study the effect of the interface on global mechanics behavior of composite.The numerical results indicate that the method developed in this paper expands the GMC in analysis of composites with complicated behavior.
