Open publisher page 0 citations

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.
