Review of Fillet Weld Strength Parameters for Shipbuilding.

Abstract

This report presents the results of a review of the current fillet weld specifications of the various classification societies and a developmental procedure for analyzing these rules by a rational method for establishing required weld size, and recommendations for further research. The results indicated large deviations among rules which relate the fillet weld size to the thickness of the base plate. The required fillet weld size by the most conservative rule may be two times that required by the most liberal rule. There appears to be a need for reviewing these rules more closely by analytical means. A computer program, named 'Automatic Dynamic Incremental Nonlinear Analysis (ADINA)', was used to determine the stress distributions in the welds of tee-joints under simple tension acting along the edges of the flange. This program could be used in determining the minimum weld sizes. A detailed explanation of the rationale of using (ADINA' program or similar FEM program is presented in this report. (Author)
