摘　　要：用有限元的方法研究了通电金属薄板裂纹尖端的温度场分布情况。模拟结果表明,由于金属薄板裂纹尖端的绕流将使裂纹尖端形成焦耳热效应,焦耳热效应能够使金属薄板裂纹尖端熔化并且形成焊口,并且半径将会显著增加,从而抑制了裂纹主干线的形成,遏制裂纹的进一步扩展。The temperature field on the crack tip in a metal sheet was studied by finite element method.Simulation results indicate that Joule＇s effect can be produced because current centralized.Joule＇s effects make the crack tip melted and form welded joints.The radius of crack tip will be increased.They will prevent the crack tip in metal from spreading.
