摘要
研究了在载流的无限大导电薄板中，瞬间形成穿透裂纹的几何尺寸（长度）、板的厚度对裂纹尖端处电磁热止裂效应的影响．通过算例表明：瞬间形成裂纹的几何尺寸是影响裂尖温度场的主要因素之一．
The effect of geometrical dimension (length andthickness) of an instantly formed penetrating crack inside aninfinite thin current-caping plate to the electromagnetic heateffect to prevent cracking near the crack tips was studied inthis paper. The geometrical dimension of an instantly formedcrack is one of the key factors which affects the temperaturcfield near crack tips.
