简要回顾了材料多轴疲劳破坏准则,引用了5种材料在单轴、比例、纯扭和90°非比例加载情况的疲劳试验结果,对基于应力、应变和能量的有关多轴疲劳破坏准则进行了分析评估.分析结果表明:应力准则中Lee准则在各种材料、各种载荷情况下均可得到误差在5%以内的较好的预测结果,但是,Lee准则中含有物理意义不明确的材料常数,需要一定量的试验数据来拟合,从而限制了该准则的应用,比例加载下,Gough准则计算简单并可适用于大部分材料;应变准则中Kandil,Brown和Miller准则和Borodii和Strizhalo准则在各种材料及各种载荷情况下都能较好的预测疲劳寿命,但Borodii和Strizhalo准则需要大量的试验数据支持,从而限制了它的应用.
