ABSTRACT

This chapter presents selected results from a series of moving load laboratory experiments on steel plates and frames, conducted using a novel moving load apparatus employing a smooth, rigid, frictionless indenter. In service ship hull-ice impact events typically consist of an initial impact with the ice feature, followed by tangential sliding of the ice along the hull. The moving sliding load scenario is also important for non-ice-strengthened ships that may encounter ice, as these ships are much more likely to experience plastic damage during ice impacts. Lateral indenter starting location is the position of the initial point of contact of the indenter with respect to the length of the test specimen’s plating. The damage on the trailing side of a sliding load can significantly impair the hull’s structural capacity—compared with stationary loads—depending on the severity of the trailing plastic damage.
