材料动态力学性能的研究是材料研究的新领域,它是研究在脉冲载荷作用下,材料处于“三高”(例如射流侵彻过程中高压达数百万公斤/厘米~2、高应变率达10~5 1/秒、高温达几千℃)受载条件下的动态响应,包括材料的物态方程,破坏强度或塑性屈服强度、应力同应变、应变率之间的关系以及动态破坏等。它和宇航、航空、核爆炸、爆 The research on the dynamic mechanical properties of materials is a new field of material research. It is the study of the material under the “three highs” under the action of impulsive loads (for example, high pressure up to millions of kg / cm ~ 2 during jet penetration, 10 ~ 5 1 / s, high temperature up to several thousands of degrees Celsius) dynamic response under load, including material equation of state, failure strength or plastic yield strength, stress and strain, the relationship between strain rate and dynamic damage. It and aerospace, aviation, nuclear explosion, explosion
