In this paper, the development of a new proof of plate capacity under combined in-plane loads for ship design and classification is described. The new proof is based on an improved understanding of plating collapse obtained from an extensive series of non-linear buckling analyses using the finite element method and covering the full range of structural configurations and load combinations relevant for the shipbuilding industry. Compared to existing proofs, the new proof incorporates a more physically based approach towards tensile stress effects on plate capacity and better captures the influences of both plate slenderness and aspect ratio under compressive biaxial loads. Moreover, the new proof can be solved without the need for iterations and may be used directly with stresses obtained from finite element analyses, thereby eliminating the need for a correction of stresses due to Poisson effects.
