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 an einkristallinen Mikrosäulen kalibriert wurde. Die Bruchparameter der Korngrenzen wurden dann im Rahmen eines Kohäsivzonenmodells bestimmt.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 experi...
