The influence on the stress distribution in an adhesive lap joint of bending of the adhering sheets

Abstract

The mathematical analysis of Goland and Reissner of the effect of deformation due to load is examined photoelastically and extended to cover a wider range of suchlike deformations. It is shown that introduction of a bending moment in the sheets opposite to that occurring in the conventional joint can produce a stress distribution on the glue line free from high normal stresses and fairly uniform in shear. A modified design of lap joint to ensure this is proposed.
