摘要

摘要: 针对合金材料在高冲击作用下的力学响应，采用分离式Hopkinson压杆（SHPB）系统确定武器弹药中常用的高强度合金30CrMnMoRE和30CrMnSi在不同应变率下的动态应力-应变关系，得到其动态应力-应变曲线及屈服强度，并结合Johnson-Cook模型对其动态本构进行拟合。结果表明，两种材料的应力-应变关系、强度等参数表现出明显的应变率相关性，随着应变率的提升，材料得到进一步强化，30CrMnMoRE的动态强度提高约79%，30CrMnSi的动态强度提高约50%。

Abstract: We conducted tests on the dynamic stress-strain relationship of both 30CrMnMoRE and 30CrMnSi at different strain rates using the split Hopkinson pressure bar (SHPB) system to study the mechanical response of alloy metal under high impact, and obtained their dynamic stress-strain curves and yield strength.And combined with the Johnson-Cook model, we obtained the dynamic constitutive model of the two materials.The test results show that the stress-strain relationship and the strength parameters of the two steels have obvious strain rate dependence.With the increase of the strain rate, the dynamic strength of 30CrMnMoRE increased by about 79%, and that of 30CrMnSi increased about by 50%.
