摘要：

A return mapping algorithm has been developed for the Hoffman yield function of anisotropic plasticity. The accuracy of the algorithm has been assessed by means of iso-error maps for trial stress increments in the deviatoric and volumetric plane. A tangent operator that is consistent with the developed integration algorithm has been formulated. The Hoffman model has been applied to a plate structure and to two shell structures. © 1990.
