Evaluation of stress integration algorithms for elastic–plastic constitutive models based on associated and non-associated flow rules

This paper presents in-depth analyses of four stress integration algorithms for finite deformation elastic–plastic constitutive relations. In particular, the four integration schemes were developed for both non-Associated Flow Rule (non-AFR) and Associated Flow Rule (AFR) in the continuum level of p...
