中文摘要: 蠕变疲劳寿命预测模型的选择是一个复杂的过程,不仅与模型的内变量相关,而且与模型构建的理论基础有关。基于损伤力学和断裂力学概述了几种耐热钢的蠕变疲劳寿命预测模型,探讨了模型的应用领域和适用性,并对耐热钢寿命预测模型的发展方向进行了展望。
中文关键词: 耐热钢  蠕变疲劳  寿命预测  模型
Abstract:Fatigue-creep life prediction is a relatively complex process,related not only to internal variables of the models,but also to the theoretical basis of model construction.The creep fatigue life prediction models of several heat resistant steels based on damage mechanics and fracture mechanics are summarized.The limitations of the application areas and applicabilities of these models have been investigated,and the development tendency of the heat-resistant steel life prediction model are prospected.
