Abstract: Highlights: [•] Grain boundary decohesion is included in a new transition rule for polycrystals. [•] Homogenized behaviour of a copper alloy under intergranular cracking is predicted. [•] A single tensile fracture test can be used to identify grain boundary parameters. [ABSTRACT FROM AUTHOR]
