Eigenstrain analysis of redisual stresses due to welding and post-weld heat treatment of aerospace materials

Abstract:

Welding, surface treatment, plastic forming and other manufacturing processes generate residual stresses and introduce distortion in engineering components and assemblies. The knowledge of residual stress states is important for the ability to predict the subsequent in-service behaviour in response to thermo-mechanical loading, including the propensity to suffer further distortion, and particularly the initiation and propagation of fatigue cracks. Inertia friction welding between Ni-base supe...
