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.Eine Methode, zur Untersuchung des Bruches einzelner Korngrenzen in duktilen Metallen, wurde auf Basis von Biegeversuchen an Mikro-Balken entwickelt. Die plastische Deformation der Biegebalken wurde mittels eines Finite Elemente Kristallplastizitätsmodells vorhergesagt, welches mit Hilfe von Druckversuchen ...
