摘要：
Polar ships and offshore platforms frequently experience repeated impact loadings in service, such as ice floe impacts, wheel loadings and impacts by platform supply vessels, which may result in some accumulated permanent structural plastic deformations and have some negative effects on their safety and work performance. This paper mainly reviews the experimental, numerical and theoretical work carried out on the dynamic behaviors of ship structures subjected to repeated mass impact loads, summarizes the mechanism of structures subjected to repeated mass impact loads, and discusses whether the structures under repeated mass impact loads will reach a pseudo-shakedown state. Besides, according to some practical repeated impacts cases, some design formulas and design curves are summarized, providing some useful information for the structural design of polar ships and offshore platforms. © 2021, Editorial Board of Journal of Ship Mechanics.
