Abstract
An elastic-plastic model that takes into account damage effects is developed and applied to masonry structures. Masonry is described as an orthotropic material and inelastic strains are governed by an associated flow rule based upon a piecewise-linear yield surface. They are split into a non-reversible (plastic) part and a recoverable part. Reversible strains are related to damage, whose effects are quantified by updating the material stiffness matrix. The model has been checked by comparing numerical results and test data concerned with masonry walls (with and without openings) subjected to plane stress states.
