Low-velocity impact behaviour and failure of stiffened steel plates
G Gruben, S Sølvernes, T Berstad, D Morin… - Marine Structures, 2017 - Elsevier
The behaviour and failure of stiffened steel plates subjected to transverse loading by an
indenter is studied in this paper. Low-velocity dynamic and quasi-static tests of stiffened
plates with geometry adopted from a typical external deck area on an offshore platform were
conducted. The results show that the quasi-static tests provide a good reference for impact
loading situations, although they displayed a larger displacement at fracture. Finite element
simulations of the steel panel tests were performed, using the elastic-viscoplastic J 2 flow …
