Résumé
The present paper describes a J2 non-associative plasticity model, which takes into account the "corner-like" effects at the loading point on the yield surface, and is suitable for shell buckling calculations. The plastic flow is based on the rate form of the deformation theory and the numerical implementation follows an Euler-backward substitution scheme. © CIMNE.
