N2 - The objective of this work is the comparison of simulated and experimentally derived local stress-strain behaviour of short glass fibre reinforced polypropylene. For the local analysis, subvolumes of interest were extracted from computed tomography (CT) data and representative volume elements (RVEs) were simulated with Digimat. The selection was based on local strains measured by Digital Volume Correlation (DVC). Two different approaches were used for the simulations: namely the Digimat-FE Abaqus solver and the Digimat-FE FFT solver. The main focus was on the elastic behaviour, nevertheless new approaches for the comparison of the strain distribution in the plastic region were presented. Overall, the results from the Abaqus solver showed a stiffer behaviour compared to the FFT solver. Furthermore, good accordance between experiments and both simulation approaches were revealed for RVEs undergoing low strains.
