The performance of an interface elastoplastic constitutive model for the analysis of
unreinforced masonry structures is evaluated. Both masonry components are discretized
aiming at a rational unit-joint model able to describe cracking, slip, and crushing of the
material. The model is formulated in the spirit of softening plasticity for tension, shear and
compression, with consistent treatment of the intersections defined by these modes. The
numerical implementation is based on modern algorithmic concepts such as local and …
