A study was conducted to develop an analytical model for predicting the horizontal resistance due to in-plane shear of ships hull bottom plating that is undergoing deformation induced by grounding. First, four models were developed for predicting the load carrying capacity of a flat rectangular plate element when subjected to in-plane shear loads in both the elastic and plastic buckling ranges. Seven plate buckling experiments were then conducted which were used to validate the analytical model results. Finally, the plate element model was incorporated into a global model description for the bottom plating of a very large crude carrier VLCC which is undergoing a deformation process induced by grounding.
