The crack arresting problem in a thin current carrying plate was studied for the situation of providing a DC current perpendicularly toward the crack direction.
研究了带有有限长裂纹的导电薄板在垂直于裂纹的方向上通入直流电流时，裂纹的止裂问题。
When the plate thickness approaches to the limit of thin plates, the current element degenerates to the thin plate element automatically, so that the shear locking phenomenon will not appear.
在薄板极限情况下，这种厚薄板通用单元自动退化为原来的薄板单元，消除了剪切闭锁现象。
With independent regulation of the arc starting, welding, and arc ending current, and the arc ending time, it has good effects in welding of both thick and thin metal plate.
具有起始、焊接、收弧电流分别调节，焊接厚、薄板都具有良好的效果。
