The results in change of in-situ temperature field and the influences of induced stress due to thermal stress field on the initial fracturecondition are analyzed.
The static effect affects only ultimate fracturecondition (the critical residual strength), while the dynamic effect affects damage evolution and residual strength degradation rate.
静态效应只影响最终断裂条件，而动态效应影响疲劳过程中的损伤演化规律和强度退化速率。

The linear fracturecondition which has been shown to be applicable to a wide variety of materials of engineering importance, is detailed with special reference to its technological significance.
