Abstract
Abstract A comparative study of the finite element analysis of the local stresses in a ship structural detail has been carried out by the members of Technical Committee II.1 of ISSC ’97. An experimental model for the intersection structure of longitudinal stiffeners and a transverse bulkhead was selected as the analysis object. Finite element analysis results of eight shell element models and two solid element models were collected for this comparative study. It is found that the results of shell element models for local stresses have high correlation with each other, but give significantly lower stresses than the experimental results. The results of the solid element model, on the other hand, agreed well with the experimental results at the weld toe. A possible interpretation of the results of shell element models, in the practical procedures of hot spot stress evaluation, is discussed.
