Analysis of Tubular Lap Joint in Torsion

Abstract

The stress distribution of the tubular lap joint whose adherends are com posite materials is analysed with a closed form solution. In the analysis the stress components, τrzand σr, which are identically zero if both adherends are isotropic materials, are introduced to satisfy the equilibrium equations and the compatibility conditions in the region of lap joint. The stress concen trations at and near the end of the joint as functions of the various parameters, such as wrap angles, overlap length, and thickness of the adhesive layer are studied.
