Longitudinally Stiffened Plate Panels Under Lateral and Axial Loads (Ship Bottom Plating).

A final summary is presented of the work performed on this research project from 1955 till 1969. A theory was developed for determining the ultimate strength of longitudinally stiffened plate panels subjected to normal and axial loads. Fifteen panel specimens were tested. Computer program output was used to develop design nomographs for panels with pinned or fixed loaded ends. Dimensions and loads were typical for ship bottom plating. The following effects were included welding residual stresses, post-buckling and post-ultimate plate behavior, different materials in stiffeners and plate. Lists are given of all research workers and of all technical reports issued by the project. Author
