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.
