This paper addresses experiment and finite element simulation studies on a small-scale double hull ship structures quasi-statically punched at the mid-span by a wedge indenter, which is intended to examine their fracture and energy absorbing mechanism. The specimen, one-sixth scaled from a tanker side panel, is account one span of the stringers in length and two spans of the web frames in width. The experiment results can provide practical information to assess the structural resistance of the ship side and bottom under collision and grounding scenarios when they suffer severe damage. In addition, numerical simulations are also carried out for the corresponding scenarios by the explicit LS-DYNA finite element solver. The experimentally recorded resistance-displacement curves and the deformation process show a good agreement with those of numerical simulations. In particular, the importance of specifying the precise jointing details and boundary conditions are also discussed.
