Abstract
Extensive experimental evidence indicates that yield surfaces exhibit significant anisotropic hardening. Subsequent yield surfaces are both translated and deformed in stress space. A viscoplasticity theory which describes anisotropic hardening by using a Lagrangian deformation mapping of the elastic domain is applied to the quantitative modelling of observed yield surface deformation of 1100-0 aluminum subject to non-proportional loading in tension-torsion space.Keywords
