Summary: Experimental residual stress measurements are compared to those obtained from numerical simulations of the welding thermal cycle for a butt welded joint. Residual stress changes due to constant amplitude cyclic loading are investigated and the ramifications with regard to durability are adressed. Shakedown events, a common industrial practice, are viewed in the context of the relaxation/redistribution of residual stresses.
