Based on evaluations of 3‐D X‐ray microtomographic reconstructions simple mean‐field and multi‐scale models were developed for predicting the plastic response of particle reinforced metal‐matrix composites. It is shown that increasing heterogeneity, by taking more details of the microstructure into account, leads to stress‐strain curves, which differ only slightly from the curve of the mean‐field model.
