A return-mapping algorithm for plastic-damage models: 3-D and plane stress formulation

Abstract

Three-dimensional and plane stress formulations of the return-mapping algorithm for a class of plastic-damage models are derived using the spectral decomposition form of the stress. An efficient plane stress computation scheme based on the spectral return-mapping algorithm is developed. The consistent algorithmic tangent stiffness for the present algorithm is formulated. The validation and performance of the present return-mapping algorithm is demonstrated by numerical examples. Copyright © 2001 John Wiley & Sons, Ltd.
