Abstract: A review is made of the literature which has been published on the theoretical and experimental plastic behavior of laterally loaded beams and rectangular plates. This article focuses attention on these particular structures since they are used extensively in marine vehicles and structural designs in general. It is well known that investigations into the static and dynamic inelastic behavior of structures are simplified considerably when elastic effects can be disregarded. It is shown herein that quite reasonable agreement can be achieved between experimental results and the corresponding rigid-plastic predictions provided that both the influence of finite lateral deflections, or geometry changes, and the effect of material strain-rate sensitivity are retained when appropriate. The results of some recent studies are also reported which indicate that extremely small in-plane displacements at the supports of beams and plates can influence significantly the structural response.
