Finite Element Analysis of Thermoviscoplastic Deformations of an Impact-Loaded Prenotched Plate
Four different thermoviscoplastic relations, namely, the Litonski-Batra, the Johnson-Cook, the Bodner-Partom and the power law are used to model the thermoviscoplastic response of a material. Each one of these relations accounts for strain hardening, strain-rate hardening and thermal softening of th...
