Abstract

Our long term aim is to provide a means of linking together finite element adaptive techniques, error estimators and stress trajectories such that a structural member with a weldment can design itself to increase its fatigue life. This paper shows that relationships can be established between base plate, cover plate and weld stresses to minimise maximum stresses and increase minimum stresses towards the goal of achieving a neutral stress field. This is shown to be achievable by altering cover plate thickness and weld leg length.
