摘要： 采用复变函数的方法,对带有曲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分析和计算,得到了电流在裂纹尖端的奇异特征,形成了点热源,进而得到裂纹尖端附近的温度场.理论计算结果与实验有较好的吻合,为计算裂纹尖端的应力场打下了基础.

关键词: 载流薄板, 温度场, 复变函数, 裂纹, 点热源, 温度梯度

Abstract: The temperature field in a current carrying plate with a penetrated curve crack under the action of transient pulse current was calculated and analyzed by using complex function analysis solution. Singularity character of the current around the crack tip was obtained. The point heat source was formed, so that the temperature field around crack tip could be deduced. The result of theoretical calculation was consistent with the experiment. It was the basis for defining the stress field around the crack tip.

Key words: current carrying plate, crack, point heat source, temperature gradient, complex function, temperature field
