基于区域叠合技术(DST)对编织复合材料渐进损伤过程进行了分析,利用ANSYS参数化设计语言建立了参数化的编织件模型,应用单元切割法在单元边与切割面交点处增加新的节点,将新增节点与该单元部分其他节点重构单元,实现从编织件模型中切割出增强相单胞模型.分别利用Hashin准则与Von Mises准则判断增强相损伤和基体损伤,根据相应损伤模式按修正的Blackketter刚度退化方案对材料刚度进行退化,应用适用于损伤分析的刚度匹配方法,实现区域叠合技术在编织复合材料渐进损伤分析中的应用.提出损伤结果映射方法,实现了基于区域叠合技术所建基体模型的渐进损伤过程的结果显示.数值分析结果发现,区域叠合法分析结果与传统方法分析结果一致,且强度和断裂应变预测结果与试验结果相吻合.
