Villavicencio, R., Liu, B. and Guedes Soares, C. (2013), “Response of a tanker side panel punched by a knife edge indenter”, International Conference on Collision and Grounding of Ships and Offshore Structures (ICCGS 2013), 17-19 June, Trondheim, Norway.
The paper presents finite element simulations of a small-scale side panel quasi-statically punched by a knife edge indenter. The panel is scaled from a tanker vessel and is limited by one span between the web frames and the stringers. The simulations describe the energy absorbing mechanisms and failure of typical shell plating structures, and evaluate the accuracy of the combined material relation and the critical failure strain predicted by tension test simulations. The calculations find that the numerical representation of the experimental supports is insignificant when predicting the force-displacement response of the specimens. However, the modelling of the support is relevant for predicting accurately the deformation and failure modes of the specimens. The results are discussed in terms of the force-displacement response and the shape of the deformation of the specimens.
