A constitutive description of tensile behavior for brass over a wide range of strain rates

In this paper, a new empirically based constitutive model, the modified Johnson–Cook (J–C) model, has been proposed to incorporate the strain rate effects on the initial yield stress and the strain hardening behavior, respectively. The new model can describe the stress–strain relation of metals over a wide range of strain rates. Based on the tensile impact recovery experimental technique, the material constants in the model can be experimentally...
