Abstract

Masonry and composite laminates are periodic in nature in their own plane. Masonry is a composite material made of units and mortar, normally arranged periodically. The combined action of brick and mortar will exhibit different directional properties. Finding the orthotropic properties or effective material properties from the individual material constituents is called the homogenisation. Less computational cost, user friendly mesh, and flexible to apply for large structures are advantages while using the homogenised properties. In this study we find the homogenised properties for unstrengthen masonry and also strengthened masonry using CFRP (inserted in bed joints). For composite laminates, homogenised properties can be found from modified rule of mixture.
