Abstract The purpose is to compare different simple plasticity models for calculating residual stresse in casting processes. Two different commercial numerical modelling programs are used. The general purpose finite element code ABAQUS and the control volume method based MAGMAstress which is developed especially for casting processes. Furthermore, another finite element code, JT, that uses the same theory as ABAQUS is used. The three different numerical models are compared with each other on a stress lattice.
