Abstract

Fatigue life analysis of various mechanical components is influenced by numerous factors. In case of welded components, fatigue analysis can be even more challenging because of additional variables that influence fatigue life in these types of structures. Many of these factors have an influence on levels of stress concentrations that are occurring in a component. Determining these stress concentrations is of foremost importance for correct calculation of fatigue life. In this paper fillet welded T-joints are modeled and finite element mesh analysis is conducted. Mesh was modeled according to IIW recommendations and results were compared to experimental data from other authors and to a simple analytical solution. Stress concentration factors calculated by finite element model analysis were found to be higher than those interpolated from experimental data, but with more consistent values for different tube wall thicknesses and different loads.
