Rectangular plates on internally distributed column supports are widely used in civil and ship structures, such as floating rafts, solar panels, and bridge decks. In this investigation, the transverse vibration of rectangular plates with internal rectangular supports and general elastically restrained boundary conditions are solved using the Raylei...

Mechanical behavior of strengthened re-entrant hexagonal unit cells for anti-collision ship side structures under quasi-static planar compression was conducted by experimental test and FEA in the present research. Four types of re-entrant unit cells which are strengthened by narrow rib, curved ribs, rhombic ribs and polyurethane foam were presented...

Engineering structures in aviation and marine experience complex loads and are often affected by repeated impact loads. The damage accumulated from deflection in the process of repeated impact will often seriously affect the safety of the structure. In this research, the low-velocity repeated impacts behavior of corrugated core structures was inves...

This paper addresses a simplified analytical method for evaluating the impact responses of the stiffeners in a ship side shell subjected to head-on collision by a bulbous bow. The stiffeners are classified as the “central stiffener” and the “lateral stiffener” according to their relative position to the bulbous bow. In analytical predictions, it is...

Experimental investigations on the mechanical responses of fully clamped circular plates with prefabricated crack at room temperature and low temperature have been conducted. Initial cracks with different lengths were prefabricated by the electrical discharge machining method. Low ambient temperature was created by the liquid nitrogen in a low-temp...
