ON THE STRENGTH DESIGN OF SHIP PLATES SUBJECTED TO IN-PLANE AND TRANSVERSE LOADING

A survey is made of the methods available for ultimate strength analysis and design of isotropic steel plates under in-plane loading and uniform transverse pressure. It is concluded that sufficient work has been carried out in formulating the elasto-plastic behavior of plates, but that no solutions have been presented for plates under combined loading of interest to ship designers. For a square panel with breadth to thickness ratio of 50, a total of 84 plate panels were tested under varying ratios of transverse pressure to edge-compression. The tests were based on a box model which consisted of four plates representing closely the conditions of ship panels. Interaction curves between the in-plane loading and transverse pressure are obtained which show the ultimate strength of the panels. It is found that for certain combinations of loading (Q/N LESS THAN 25) the plates undergo a sudden collapse due to plastic instability while for other load combinations the plates exhibit excessive plastic deformation with load increments. The effects of residual stresses and initial deformations are investigated. Proposals are made for the further development of the theoretical work and the extension of present experimental program.
