damage tolerant design meaning in Chinese

破损设计
损伤容限设计

As it is difficult to obtain the accurate analytical solutions for the stress constraints of general 3d cracks , we have conducted systemically detailed researches on the out - of - plane stress constraint by finite elements ( fe ) and proposed a two - parameter description of non - through thickness 3d crack fields . several problems in damage tolerant design were also investigated based on continuum mechanics and probability theory
三维应力约束对精确预测结构破坏不可缺少,因此,本文采用三维有限元等方法基于连续介质力学、概率论等理论,对典型三维裂纹尤其是非穿透裂纹系统深入地开展了三维应力约束理论计算、三维裂纹端部应力场描述以及结构三维损伤容限设计的研究。
