Abstract

Abstract: Computational Fluid Dynamics (CFD) and Fluid-Structure Interaction (FSI) based modelling and simulation techniques have been developed in the present research to investigate adhesion failure analysis in bonded tubular socket joints. Joint parameters like gap between the adherends, adhesive thickness, and overlap length have been optimized so as to minimize stress concentration effects localized to the joint edges under turbulent flow modelled through a realizable k-ɛ model. Adherend-adhesive and socket-adhesive interfaces in the joint region have been identified to be the critical bond line interfaces prone to failure under turbulence. Three-dimensional out-of-plane stresses (σrr, τθr, τzr ) critically responsible for adhesion failure have been studied leading to evaluation of Parabolic yield criterion used to identify the failure prone zones.
