International audience; Polycrystalline microstructures occur in nature and also arise in industrial processes. Performing finite element computations on such microstructures is relevant in multiple engineering fields. The present paper describes a h

A flexible, general and stable mixed formulation is developed to model distributed cracking in cohesive grain-based materials in the framework of the extended/generalized finite element method. The displacement field is discretized on each grain sepa
