Abstract: In this contribution, a rate-dependent mesoscopic masonry model is presented in which the mortar joints are incorporated by embedded weak discontinuities based on partitions of unity. Within the discontinuities, both an isotropic damage and a Perzyna viscoplastic model are used to describe joint degradation. The elastic domain of the joint behaviour is bounded by a modi ed Drucker-Prager yield function. The performance of the developed masonry model is demonstrated by the simulation of a three-point bending test and a shear wall test.
