The present work attempts the application of shakedown plastic analysis in the design of hull plating panels subjected to lateral slamming loads. The purpose is to utilize the additional strength of the panels which suffer excessive loads, beyond the elastic limit and up to a certain shakedown condition. The repeated nature of slamming loading is considered quite appropriate for this analysis. The phenomenon is examined from the structural designer's point of view. In order to gain valuable insight from accumulated experience, comparisons are made with American Bureau of Shipping and Lloyd's Register of Shipping Rules. A parallel comparison with plastic design results is also carried out and recommended design scantlings are proposed for the cases at hand. The final part approaches the problem from its economic side and attempts to analyze the impact of relevant earlier decisions and trade-off analyses in design stages, over the life cycle cost and productivity of a ship.
