Study on Dynamic Mechanical Behaviors and J–C Constitutive Model of a Fine-Grained D6A Steel

Study on Dynamic Mechanical Behaviors and J–C Constitutive Model of a Fine-Grained D6A Steel

The uniaxial tensile loading tests of coarse-grained D6A steel (CG, d = 20 μm) and fine-grained D6A steel (FG, d = 1.5 μm) were performed using a material testing machine and rotating disk Hopkinson tension bar, respectively. The stress–strain curves of two steels at different strain rates (0.001~15...
