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. Main objectives of this work consist of FE modelling of shakedown in welded samples, followed by experimental validation using fatigue loading tests in conjunction with stress measurement using Neutron diffraction technique. This project has chosen an industrially relevant sample and load levels owing to the fact that these contributes to the variation in the overall residual stress redistribution.
