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.
