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。
The average dynamic yield strength σ_s of three types of steel (D60, 58SiMn, 9260) in the strain rate ε = 10 ~ 3 ~ 10 s ~ (-1) ~ 4 was studied by using the impact loading experiment and energy balance theory model ~ D and related features. Based on the Taylor model, the history of the dynamic yield limits of materials over time during loading is discussed.
