Influence of residual welding stresses on the fatigue behavior of tubular K-joints in compression Ghent University
The fatigue susceptibility of tubular bridges, composed of circular hollow section profiles welded together in Kjoints,
is due to stress concentrations, to welding imperfections and to tensile residual weld stresses. Since the
residual stress distribution is largely unknown, this research wants to determine the actual distribution using the
hole-drilling method on actual samples, combined with FE calculations. ...
