Abstract
The present paper discusses on the modeling of ship deck panels at concept design stage using Equivalent Single Layer (ESL) plate theory. First order shear deformation theory is utilized that enables modeling of one-side stiffened plates used traditionally in shipbuilding, but also double-skinned structures such as sandwich plates and composite structures. Interaction between the plate element and supporting girders is modeled using offset beams. The static, vibration, bifurcation buckling and post-buckling response are considered. The validation is done with fine mesh FE-analyses based on modeling the actual 3D topology with shell elements. The paper shows that ESL is very efficient way to model and optimize the ship structure where differences of scale, as well as the complexity of the geometry, cause difficulties for the Finite Element discretization as well as to the solution. The benefit of the method is that FE-mesh needs to be created only once. This enables optimization during the design by changing only the equivalent stiffness properties of the beams and plates leaving the mesh unchanged.
