摘要
本文从线弹性理论比应变能的概念出发,应用裂纹尖端区域应力场的分布规律,推导出描述复合材料断裂行为的一种损伤因子理论,该理论具有明确的物理意义。
In this paper, a new damage factor of composite material is derived which has obvious and definite physical meanings based on the concept of rate strain energy in linear elastic theory, by applying the distribution of stress field in the crack tip region.
