Abstract: This paper describes the application of a domain decomposition technique for multiscale modelling of fracture behaviour in masonry. The use of multiple domains allows for a di fference in employed mesh sizes for the macro- and mesoscale. For domains which play a crucial role in the failure process, we apply a mesoscale level meshing, while less critical components can be modelled by a less computationally expensive macroscale mesh. The crack behaviour is modelled by using the GFEM method, while the joint degradation is described using a plasticity based cohesive zone model, with a smooth yield surface. For the purpose of domain decomposition, we propose the use of a FETI method.
