Contributions to the anisotropic elasto-plastic analysis of shells

[摘要] (cont.) Finally we review a constitutive model for anisotropic elasto-plastic analysis which takes into account the anisotropy of both the elastic and plastic material behaviors, as well as their evolution with plastic strains. It is based on continuum energy considerations, the Lee decomposition of deformations and a stored energy function of the logarithmic strains. The present work focuses on giving some physical insight into the parameters of the model and their effects on the predictions in proportional and in non-proportional loading conditions.
