摘　　要：用炸药透镜发生的平面波,对两种装甲钢进行冲击,研究层裂试样,发现普通的装甲钢由于夹杂比较多而且尺寸比较大,所以其裂纹在夹杂处发生并合并;而对于洁净钢的裂纹则发生在晶界,并沿着晶粒尺寸比较小的方向扩展。应用材料学、断裂力学等原理进行分析,提出提高装甲钢抗冲击能力的措施。In paper, it is researched, that layer-crack specimens of tow type armour steels is impacted by plane wave occurred use dynamite lens . Result show: Crack is occurred and united at lards for general armour steel take on more number and more size; but crack is occurred at grain-bound and extend along fine-grain way for lustration armour steel.At one time, the test result is analyses by material science and fracture mechanics, and measure of increasing faculty anti-impact for armour steel put forward.
