摘要

The σ-ε relation of ship low-carbon steel under different strain rates (0.0002~3900 s^-1) was studied experimentally with the MTS (Materials test system) and the split Hopkinson press bar (SHPB), two improved Cowper-Symonds models and the parameters were obtained, and then the applicability of the models was investigated. The experimental results show that the low-carbon steel has a remarkable strain rate effect and a nonlinear strain hardening effect. Dynamic constitutive model of ship low-carbon steel can describe the dynamic mechanical behaviors under high strain rate. Application of the CS models should be careful when strain rate is higher than 2000 s^-1.
