Abstract
This paper describes a numerical study of the stress distribution in pin-loaded lugs. The effects of : (i) the ratio of lug width (w) to hole diameter (d), (ii) the ratio of the distance of the hole centre from the free end of the lug (h) to hole diameter (d), and (iii) the pin interference/clearance, on the magnitude and position of the maximum circumferential stress around the hole in the lug are established and discussed. Pin fit is shown to be a particularly important detail and the beneficial effects of an interference fit are shown to be considerable. It is also shown that for ratios w/d greater than 4 and h/d greater than 3 there is little variation in the maximum circumferential stress for a given applied load.
