摘要: Abstract The sheet metal ductility for a thermoviscoplastic material is analysed by using perturbation method. A significant rate of growth the instability characterized in terms an effective analysis. Analytical results are obtained quite general behavior (including time-dependent effects). They match Hill (1952. J. Mech. Phys. Solids 1 , 19) and Storen Rice (1975, 23 421) time-independent behavior.
