Analysis of bonded tubular single lap joints subjected to varying pressure at constant torsion

摘要

The effect of internal pressure coupled with torsion on the bonded socket joints with laminated FRP composite pipes as adherents has been studied in the present research. Influence of internal pressure conditions which are most commonly experienced during flow of various fluids, has been taken into account under constant torsion. Finite element method (FEM) based modelling and simulation technique, capable of detailing the three-dimensional stresses along with fracture analysis of the bonded joint has been used. The effect of pressure on the adher end-adhesive interfaces, which are vulnerable to adhesion failure has been analyzed through the modelling technique.
