摘要
从热力学理论的框架出发，采用内变量理论，研究了硬化对裂纹尖端温度的影响。还按Ｌｅ－ｍａｉｔｒｅ－Ｃｈａｂｏｃｈｅ的损伤理论，考虑了损伤对裂纹尖端温度的影响。结果表明。
On the basis of thermodynamics principles, the effect of hardening on the temperature of the crack tip is studied by using internal variable theories. It also considers the effect of damage on the temperature of the crack tip according to Lemaitre Chaboche damage principles. It concludes that latent heat has nneligible effect on the temperature distribution.
