Homogenisation of masonry structures subjected to seismic loads through matrix/inclusion micromechanics

The mechanical properties of masonry, both in the linear elastic range and after onset damage, are dependent on geometric its constituent materials: units mortar. Finite element micromodelling, while capable providing accurate comprehensive results, is associated with high computational costs modelling effort. On other hand, micromechanical homogenisation masonry composite provides an attractive alternative to detailed which stress strain interaction between material phases can be modelled without excessive cost interpretation damage state more straightforward. However, nonlinear elements through varied numerical analytical approaches remains a subject intense study. In this paper, inclusion-based scheme for structures proposed plane conditions. combined constitutive laws materials implemented finite models. approach validated terms capacity predict against experimental results benchmark. Finally, analyses walls subjected in-plane shear under varying levels vertical performed favourably compared predicted obtained failure mode. low model makes it suitable future application digital twinning operations.
