He, X. and Guedes Soares, C. (2024), Recent developments in ship structures subjected to repeated impact loadings, Advances in Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.). Taylor and Francis, London, UK, pp. 407-415.
This paper aims to enhance the understanding of dynamic response of ship structures subjected to repeated impacts and consequently to offer some useful guidance for anti-repeated impact design. Repeated impacts are ones of the most common loading scenarios in ship and marine engineering, such as ice floe impacts, slamming, and minor collisions between supply vessels and offshore platforms. Repeated impacts are prone to accumulate plastic deformation on ship and marine structures, even worse, leading to structural failure. This paper reviews recent works on ship structures subjected to repeated impacts. The characteristics of dynamic response of structures under repeated impacts are demonstrated based on numerical and experimental studies. Special attention is given to pseudo-shakedown analysis under repeated impacts. The advantages of pseudo-shakedown phenomenon in withstanding repeated impacts are discussed.
