Abstract

Abstract

Temperature field at the time of pulse current discharge in metal structure with elliptical embedding crack was theoretically analyzed.In the progress of getting the temperature field,the current flows past an elliptical embedding crack is similar to the fluid flows past a barrier according to similarity principle.The boundary condition deriving from this theory was introduced so that the distribution of the current density and the temperature field expressions are gotten.The basic theoretical study for the actual application of spatial crack arrest is carried on by electromagnetic heating.
