研究材料在高速变形下的动力学性质与提高各种兵器的综合战斗性能有着密切的联系。例如,穿甲弹或破甲弹形成的高速射流侵彻装甲钢板时,弹和板发生两种形式的变形:一是连续的弹塑性流动;二是各种形态的动态破坏,如径向开裂、崩落、压碎和绝 The dynamic properties of the materials under high-speed deformation are closely linked with the improvement of the comprehensive combat performance of various weapons. For example, when a high-velocity jet penetrating an armor-piercing projectile or an armor-piercing projectile penetrates an armored steel plate, the projectile and the plate undergo two forms of deformation: one is continuous elastic-plastic flow; the other is dynamic damage in various forms such as radial cracking and caving , Crushed and absolutely
