000014329 520__ $$2eng$$aIt was experimentally observed in the literature that damage during low cycle fatigue of polycrystalline nickel-based alloys initiates in the areas with highly localized plastic strains. In our study alloy-R88DT with densely populated annealing twins, the interface between the twin and the parent grain is especially prone to local damage since it coincides with the slip planes. This is mor e evident when the interface is characterized by high Schmid factors and low elastic modulus grain. Crystal plasticity simulations are performed in order to identify numerically the microstructural factors, such as crystalline orientation of the grain±twin pair, elastic properties of the grain and twin, twin geometry, promoting high total stain in the material and thus high probability of damage. Maps indicating the strain localization are provided in the space defined by grains/twins orientations at high temperatures where multiple types of slip systems are activated.
