Structural damage and strength criteria for ship stiffened panels under impact pressure actions arising from sloshing, slamming and green water loading


Author(s): J.K.Paik and Y.S.Shin


Abstract:
Ship structures while in service are likely to suffer structural damage due to impact pressure actions arising from sloshing, slamming, or green water. The aim of this article is to develop closed-form design formulations for predicting structural damage of ship stiffened panels under impact pressure loads. Existing formulations of permanent panel deflection developed under quasi-static pressure loading condition in the literature are expanded to account for the dynamic effects associated with the impact pressure actions. The validity of the proposed method is confirmed by a comparison with the present DYNA3D numerical simulations for ship stiffened panels and experimental results where available. It is our hope that the insights and design formulations developed from this study will be useful for strength design of ship structures against sloshing, slamming, or green water.
