Finite Element Fatigue Stress Analysis of Cruciform Welded Joints

Abstract

The stress distribution of cruciform welded joints was analyzed by finite element codes ABAQUS. Two models, one without the weld line and another with the weld line, were investigated. The meshes were generated by the way of swept mesh and structured mesh. Uniform mesh and transition mesh were implemented. Different ways of mesh generation were compared, and the model of transition mesh by the way of structured was thought to be better for the stress concentration expression.
