材料多轴疲劳破坏准则回顾

Review on the multiaxial fatigue criteria

对多轴疲劳载荷作用下材料的疲劳破坏准则作了系统的回顾 ,按照用于描述材料疲劳破坏的参量 ,将多轴疲劳破坏准则划分为三类 ,应力准则、应变准则、能量准则。分别对这三种准则按多轴比例加载及多轴非比例加载两种情况进行阐述 。

Some commonly used multiaxial fatigue criteria were systemically reviewed. According to parameters which were used to describe fatigue damage of material, the criteria were classified into three viewpoints. They are criteria based on stress, criteria based on strain, and criteria based on energy. The criteria in each viewpoint were classified into two groups, depending on they were suitable for multiaxial proportional loading or multiaxial non proportional loading. Some problems which existed in those studies were examined, and a concise assessment was provided.
