English abstract:
The present paper deals with elastoplastic finite strain simulations of particle reinforced Metal Matrix Composites (MMC) as well as parts and specimens made thereof. An Incremental Mori-Tanaka method is employed as constitutive material law which describes the MMC's behavior within structural analyses by the Finite Element Method. The predicted response of the MMC component is compared to simulations from unit cell predictions by the Periodic Microfield approach. Excellent agreement is found for the composite behavior even for complex non-proportional loading histories. For the micro stress and micro strain fields in the constituents, the predictions of the unit cells are superior.
