Dislocation-dynamics based crystal plasticity law for the low- and high-temperature deformation regimes of bcc crystal

Based on recent dislocation dynamics simulations investigations, a set of constitutive equations and model parameters for the description of plasticity of body-centered cubic materials is proposed. Assuming the flow stress to be controlled at low temperatures by the mobility of screw dislocations an...
