摘要
通过研究裂纹扩展的热效应,提出了包含热效应的本构关系及裂纹扩展条件,建立了裂尖温度场模型,确定了温度分布函数,并进行了相应的实验,理论与实验结果吻合较好.
First,the constitutive equations and crack propagation conditions are proposed.Then,the crack tip temperature field model is established and the function of the tempera-ture distribution is derived. Finaly,the experiment is performed. The calculated values a-gree with the experimented results well.
