Plastic deformation of plates in deck structures under wheel loads of heavy vehicles or helicopters is common in ships and offshore structures, which is a design aspect of significant interests to the designers of ro-ro/cargo ships, naval ships and offshore platforms. Important work on this topic is reviewed in association with recent development and the design principle of wheel patch loaded plating is studied together with the design criteria. The nonlinear response of ship plates is investigated by using nonlinear finite element simulations. A simple formula based on the relationship between the lateral load and permanent deflection of plates is proposed, which compared with the nonlinear FE analysis. The design formula to determine the plating thickness is derived based on the level of allowable permanent set. Comparisons are made with Hughes design formula and Jackson & Frieze design curves, and it shows that the proposed design formula is promising for practical design of ship deck plates.
