Abstract
Assuming a generalized strain hardening curve whose form is independent of the hydrostatic component of the stresses, the effect of pressure on the ductility of metal subjected to some simple sheet forming processes is calculated. The metal is assumed to be isotropic and to obey the v Mises yield criterion and its associated flow rule. In all cases considered, the ductility is increased by the presence of fluid pressure on the sheet surface.Keywords
