Abstract
In the paper, the author is focusing on the torsion dynamic analysis of the ship hull made of composite materials. The numerical analysis (using two methods, one of them being a new proposed method) and experiments are developed on a simplified typical hull of a container ship. The aim of the work is to analyze the influence of the very large open decks on the dynamic torsion behavior of the ship hull. The torsion analysis is performed on a scale model (1:50) of a container ship, made of layered composite material. The first five natural frequencies are determined with the proposed numerical method (software code TORS) and are compared with the results obtained with FEM package soft COSMOS/M and with the experiments.
