Numerical strategies for solving continuum damage problems involving softening : Application to the homogenization of masonry
The homogenisation theory for periodic media is used for deriving the in-plane macroscopic non-linear behaviour of masonry. Two different assumptions are envisaged, plane stress and generalised plane strain. Assuming a continuum damage modelling for the brick and the mortar, the two-dimensional boundary value problem associated with the homogenisation method is investigated, together with the numerical strategies able to solve it. The numerical difficulties related to the softening character of the constitutive law are emphasised. The results obtained for typical loading paths are presented. The effect of the head joints is significant and only the generalised plane strain assumption leads to realistic results.
