中文摘要：

利用孕育时间准则建立金属从弹性到塑性状态的转变模型，这种方法类似于在St．-PetersburgStateUniversity发展起来的脆性固体断裂的结构暂存理论．该方法可使我们建立模型，很好地分析和解释材料随温度变化发生的屈服应力演化、韧-脆性失效转变及其他效应等特殊的力学现象．

英文摘要：

Transition of the materials from elastic to plastic state is modeled by incubation-time based criterion. This approach is similar to the structural-temporal theory for brittle solids fracture developed in St.-Petersburg State University. This approach allow us to model anomalous behavior of yield stress in case of elevated temperature, brittle-to-ductile failure mode transition and some other effects.
