The Research on the Stress Concentration Factor of T-Joints Subjected to Axial Load

Article Preview

Abstract:

By terms of the numerical modeling of ABAQUS software, the analysis of the stress concentration factor (SCF) of tubular T-joints subjected to axial load is analyzed in this paper. The magnitude and the distribution of the SCF are also obtained. Through the finite element analysis of 816 models, the effect of geometrical parameters on the value and distribution of the SCF is investigated. Then based on these results, the parametric equations of the maximal SCF and SCF distribution for T-joints subjected to axial load are presented. Error analysis of these parametric equations is also carried out.
