Stress concentration factors of multi-planar tubular KT-joints subjected to in-plane bending moments
Abstract Numerical research on the stress concentration factors (SCFs) in uniplanar tubular joints is abundantly reported in literature. However, it has been shown that SCF equations for uniplanar joints can lead to both under- or overestimation of the SCFs in multi-planar joints. In this paper, a parametric finite element study of 81 different three-planar KT joints subjected to five different in-plane bending loading conditions is performed. The effects of different non-dimensional geometrical parameters on the SCF values at the crown locations of the central and outer braces are studied. Based on nonlinear regression analyses of the finite element results, a new set of SCF equations is developed and presented.
Highlights Stress concentration factors at central and outer braces are studied for three-planar DKT joints. Effects of non-dimensional geometrical parameters on the chord-side SCFs are quantified. 81 FE models subjected to the five in-plane bending loading modes were studied. 39 parametric formulas are presented for stress concentration factors.
