A compared study of the shape’s plate behaviour under the impact load

A major stage in the naval design is to establish the structural resistance of the ship body. Non-linear FE analysis methods are used for determination the hull's structural capacity. The plates and the beams are important constructive elements of the ship structure. This paper presents a compared study of the impact analysis of the plates with different curvature. Both non-linear static and dynamic analysis are made to understand the structural behaviours of the plates. It deals with determining the deformations and stresses obtained from implicit static and explicit dynamic analysis. In order to evaluate the influence of shape plate on structural behaviour, the energy dissipation is observed by calculating the absorbed energy. The main results will be used in the process of optimisation the ship body's shell shape.
