Increasing application of composite structures in engineering field inherently speed up the studies focusing on the investigation of non-homogeneous bodies. Due to their capability on capturing the size effects, and offering solutions independent of spatial discretization, enriched non-classical continuum theories are often more preferable with respect to the classical ones.
The aim of the present work is to investigate the mechanical behaviour of orthotropic masonry subjected to localised loads in the context of both ‘implicit’/‘weak’ and ‘explicit’/‘strong’ non-local continuum models. To look for possible correspondences and differences, the solutions of Cosserat (micropolar) and integral form of Eringen models, obtained by employing finite element method, are compared. The resulting displacement and stress fields highlight the diffusive character of micropolar model, and the capability of Eringen model in avoiding stress singularities.
