Abstract
The objective of this paper is to analyze the structural dynamic buckling strength of containership bow structures subjected to impact force using finite element method. In this study, a containership bow structure designed and constructed by CSBC Corporation, Taiwan is modeled and solved by geometric nonlinear and transient dynamic programs; and the wave impact pressures are obtained through applying the semi-empirical formula established by Lloyd's Register. Furthermore, one-time thickness deformation method and buckling failure method are employed here to determine the initial buckling load of bow structure. The results show that the impact force integration is the dominant factor for structure buckling strength assessment. This conclusion offers the designer an effective and efficient way to predict the structure dynamic buckling strength; moreover, it is can help the designer realize the moment when the structure happens buckling under any different impact force case. ? 2011 Taylor & Francis Group, London.
