Notes:
In pinned connections, the presence of an initial clearance increases the lug stressconcentration with respect to a neat fit configuration. By employing a recently proposed loadingparameter Φ valid for plane models, the applied load and initial clearance effects on the stressconcentration are normalised for a straight-shanked, round-ended, longitudinally loaded pin-lugconnection of fixed outer to inner radius ratio. Results are obtained with a Mitchell-type, Fourierseries solution and with commercial Finite Elements. The applicability of the loading parameter Φto pinned connections with small to relevant initial clearances is explored. Two preliminary designcharts are presented, which quantify the lug stress concentration factor versus the loading parameterΦ for two lug geometries defined by inner to outer radii ratios of 0.376 and 0.77
