A simple method based on plastic theory is proposed to study the ultimate torsional strength of ship hulls. The plastic theory and a finite element analysis are used to analyze the collapse of a test specimen in torsion so as to compare with the experimental results. A computer program using one-dimensional finite element method is used to analyze the elastic behavior of the test specimen, and a nonlinear finite element method is used to analyze in detail its plastic behavior. The study is mainly concentrated on the section that is the transition from open to closed section. Special attention is paid on the comparisons of different calculation results.
