N2 - In this contribution experimental and theoretical investigations of sheet metal mesocrystals with coarse texture are performed. One focus of this work is on size effects due to a lack of statistical homogeneity. The overall mechanical response is then strongly influenced by the orientation of the individual grains. For this purpose a crystal-plasticity-based finite-element model is developed for each grain, the grain morphology, and the specimen as a whole. The crystal plasticity model itself is rate-dependent and accounts for local dissipative hardening effects. This model is applied to simulate the thin sheet metal specimens with coarse texture subjected to tensile loading at room temperature. Investigations are done for body-centered-cubic Fe-3%Si and face-centered-cubic Ni samples. Comparison of simulation results to experiment are given.
