Popis: Design of hull plating based on a plastic failure criterion is discussed in this paper. The plating is loaded by high lateral pressure, e.g., slamming or ice loads. The process of plastic deformations as a function of load is analyzed. Experience in establishing in-service permissible permanent deformations of plates is considered as well as early experimental data of plastic failure of plates. Formulations are developed for permanent plastic deflections preceding the plate's failure coupled with a diagram for calculating the plate's permanent deflections when the plastic deflections became large. Sample calculations in this paper are based on the scantlings of a U. S. Coast Guard cutter.
