By means of a constrained expansion and a free expansion explosion tests, the deformation and crack characteristics and the formation rules of fragments of the cylinder walls made of five kinds of materials under the condition of explosive loading were investigated.

采用约束爆破和自由膨胀爆破两种实验方法 ,研究了工业纯铁 ,Mn -B系空冷贝氏体钢等五种材料在爆破加载条件下管壁变形、开裂特征和破片形成规律。
