Investigation of shake-down effects on residual stress redistribution in ship structures

Abstract: The fact that residual stresses are redistributed or relaxed during operations shows the importance of understanding residual stress after a particular period. Elastic shakedown is a phenomenon in which the structure undergoes plastic deformation accompanied with a change in residual stress during the first few cycles followed by an elastic response. As a consequence, residual stresses are redistributed or relaxed. The principal aim of this experiment is to investigate the initial, as-welded distribution of residual stresses and their relaxation as a result of shakedown in T-joints. Dh-36, a typical ship structural steel is used to manufacture T-joints based on ship welding standard. This project has chosen an industrially relevant sample and load levels owing to the fact that these contribute to the variation in residual stress redistribution.
