摘要
利用撞击加载实验法和能量平衡理论模型,研究了三种弹钢(D60,58SiMn,9260)在应变率ε=10~3~10 s^(-1)~4范围内的平均动屈服强度σ_s^D和相关特性。在Taylor模型基础上,讨论了在加载过程中材料动屈服限值随时间的变化历史。
Average dynamic yield strengths and correlative characteristics for three kinds of steel(D60,58SiMn and 9260) are studied up to strain rates of 10~3~10~4s^(-l),using the impact compression test and energy balance theory.Besides,the dynamic yield point history of materials during impact is discussed based upon Taylor's momentum model.
