Influence of grain boundary conditions on modeling of size-dependence in polycrystals
Journal article, 2011

In this paper, a gradient crystal plasticity model in a polycrystalline grain structure is investigated. Hereby, the focus is on the influence of the grain boundary conditions. A new type of grain boundary conditions is introduced, the so-called micro-flexible boundary condition. In particular, it is compared to existing grain boundary conditions of plastic slip. Numerical results are given for the stress-strain response as well as for the plastic slip field in the grain structure.
