In this paper, based on Finite Element (FE) simulation, the ultimate strength of damaged continuous plating is studied considering the combined effect of residual deflections and stresses. Firstly, damage over plating is simulated resulting to residual deflection in prescribed shape and magnitude accompanied by residual stresses. Then compressive loading is applied and the effect of simultaneous presence of both residual deflections and residual stresses on the plating ultimate strength is studied. It is found that (1) the compressive strength may be significantly overestimated when the damage related residual stresses are not considered, (2) a larger magnitude of initial dishing does not necessary result to a lower ultimate strength. It is shown that the simplified methods in the Common Bulk Carrier Rules need further improvements.
