Three phenomenological yield criteria are adopted to describe the plastic behaviour of sheet metals with normal plastic anisotropy. The sheet metals are assumed to be elastic-plastic, rate-sensitive and incompressible. A rate-sensitive thin shell ΓΏnite element formulation based on the virtual work p
A yield function that describes the behavior of orthotropic sheet metals exhibiting planar anisotropy and subjected to plane stress conditions is proposed. It is shown to give a reasonable approximation to plastic potentials calculated with the Taylor/Bishop and Hill theory of polycrystalline plasti
