摘    要:采用复变函数方法对带有两个共线穿透裂纹的导电薄板,在瞬间电流作用下的温度场进行了计算。针对带有两个共线裂纹或夹杂的载流薄板形成了边值问题,给出封闭形式的解,得到了电流在裂纹尖端的奇异特征。在形成了点热源的基础上,导出裂纹端附近区域的温度场表达式,为计算裂纹尖端附近应力场打下了基础。

关 键 词:载流薄板 裂纹 点热源 温度梯度 温度场

Abstract:In this paper, the temperature field in an current-c ar rying plate with more than one collinear penetrated cracks under the action of t ransient pulse current was calculated by using complex function methods. consid ering to the plane with more than one collinear cracks, the boundary value probl em was formed an d the analytical closed form solution of given. Singularity cha racter of the cur rent around the crack tip was obtained, and the point heat sou rce was formed, so was that the temperature field around crack tip was educed. It was the basis of defining the stress field around the crack tip.
Keywords:current-carrying plate   crack   point heat source   te mperature gradient   temperature field.
