摘要：

The sheet metal ductility for a thermoviscoplastic material is analysed by using a perturbation method. A significant rate of growth of the instability is characterized in terms of an effective instability analysis. Analytical results are obtained for quite general material behavior (including time-dependent effects). They match the results of Hill (1952. J. Mech. Phys. Solids 1, 19) and Stören and Rice (1975, J. Mech. Phys. Solids 23, 421) for time-independent behavior. © 1990.
