A closer look into the predicted large strain response and plastic shear instability behavior derived from the so-called Z-A equations, incorporating thermally activated yielding of bcc metals (due to their high Peierls stresses) and thermally activated strain hardening of fcc metals (produced by dislocation intersections), shows the need for including dynamic recovery effects in the strain hardening for both bcc and fcc cases. Recovery effects are observed in the stress/strain behavior of… CONTINUE READING
