Abstract: In plastically deforming polycrystals, grains interact with their surroundings resulting in heterogeneous deformation fields both at inter- and intragrain level. When the crystal plasticity finite element method (CPFEM) is employed to predict such heterogeneity, splitting of grains is occasionally observed. In the present study, detailed local strain analysis is performed in such subdivided grain and its neighbors. The role of local interactions at the grain boundaries and of the initial orientation of the grain is investigated. It is shown that a hard grain surrounded by relatively softer grains is prone to subdivide when subjected to opposing shears.
