Low-cycle fatigue of ship hull damaged in collision

I Gledić, J Parunov, P Prebeg, M Ćorak - Engineering failure analysis, 2019 - Elsevier
This work aims to extend the conventional post-accidental structural safety assessment by
investigating the possibility of damage propagation in a damaged ship during the salvage
period as a low-cycle high-stress fatigue process caused by fluctuating wave loads. Low-
cycle loading can cause high-amplitude stresses at the edge of the damage opening, which
consequently lead to high-stress concentrations. In the present study, a finite element model
is created for an intact ship and 50 random damage scenarios for which the stress …
