✦ Synopsis

Mode I stress intensity factors for a symmetrical lug with a through radial crack emanating from the internal boundary were evaluated with finite element techniques. A new geometric conhguration was developed which saves a minimum of 60% in computer time over the traditional configuration. The effect of interference fit and slip fit was investigated by comparing the results obtained for two different loading conditions; point force and uniform bearing pressure distribution, of which, pin loading yields the larger stress intensity factor. A means of estimating the residual life is also presented.
