Finite Element Analysis of Ship Deck Sandwich Panel

摘要

Recently various types of sandwich panel are applied for constructing bridge and ship structures. Sandwich panel is material that consists of lightweight core material and two metal faceplates. The application of sandwich panel in ship structures makes the structure less-complex and ship's self-weight lighter because of the reduction of secondary stiffeners. This paper discusses sandwich panel that was fabricated using synthetic resin core material and two steel faceplates. This study is aimed to analyze stresses developed in the sandwich panel of 750 GT Ro-Ro ship car deck structure when it was subjected to the deck design load. The finite element analysis was carried out to obtain the stress distribution and maximum deformation on the car deck structures. The stress of the ship car deck constructed using conventional steel structure, i.e. steel plate and stiffener, was compared with the stress of the deck that was built using sandwich panel.
