Abstract
Understanding of interfacial effects between the components of composites is essential and masonry and concrete are materials which are not completely understood, Photoelastic techniques have been used to study the effects of inhomogeneity in concrete. Arnold Hendry was a recognized expert in the field of photoelasticity, yet when he initiated study on interfacial effects in masonry, he encouraged computer modelling by Finite Elements. By comparing results of photoelastic and strain gauge assessments of strain in concrete, and the results of the finite element analysis of the brick-mortar interface by one of Arnold Hendry’s students with the results from our own 3-D analysis, we trace part of Hendry’s immense contribution to engineering, and masonry in particular.
