A method to investigate the fracture of a single grain boundary in ductile metals is developed based on micro-cantilever bending experiments. The plastic deformation of the cantilevers is predicted by a finite element crystal plasticity model which is calibrated making use of micro-compression experiments on single crystalline micro columns. The fracture parameters of a grain boundary are then determined in terms of a cohesive zone model.
