Review of Detail Meshes for Application to Fatigue Analysis

Abstract

Methods for determining the stress range in regions of high stress in ship structural !details are described with emphasis on the hot spot method for fatigue analysis. Finite !element models oftypical details were created and analyzed to determine the hot spot stresses at the weld toe. Models of details with cut-outs were also analyzed by using !essentially zero stiffness bar elements to determine the hot spot stresses at the plate edges pfthe cut-outs.
