Abstract
ABSTRACT
Wrinkling in deep-drawing process was analyzed as the form of short-wavelength
shallow buckling modes based on the Donnell-Mushtari-Vlasov shell theory. The local
analysis considered the current deformed state of a sheet element in a doubly-curved,
biaxial plane stress state. The yield criterion for mixed-hardening metal used J2 yield
criterion for isotropic metal and Hosford’s yield criterion for anisotropic metal. The effect
of back stresses on wrinkling limit curves was investigated numerically.
