Structural analysis of midship section using finite element method

The design used in the present work is from the conceptual design of a container ship and includes preliminary analysis of the structural design of the midship section. The main objective of the work is to study the structural response of the midship section to static loading. The present work is carried out in ANSYS, which is well-known finite element modeling software. The first step is to produce the required model in ANSYS, which we can either model in ANSYS or can import from any CAD software. For this analysis, the model has been developed in ANSYS Parametric Design Language (APDL). As it is a preliminary analysis, there are many assumptions, such as reducing the number of girders and longitudinal stiffeners. The different static forces taken into account are the hydrostatic pressure acting on the ship's hull, the self-weight of structural members, and the loads from containers. There are two approaches for load application: the load combination method and the resultant force method. In the first method, we apply the forces acting on each structural member. In the second method, we find the resultant forces and these are applied on some respective structural members.
