Effects of clearance and interference on stress intensity factors are considered for radial cracks emanating from a pin-loaded hole in a finite width strip.
Photoelastic results of stress intensity factors for several clearance and interference pins are given for selected combinations of sheet-width to hole diameter ratio and crack-length to sheet-width ratio. It is shown that the stress intensity factors of pushfit pins are less than those of clearance and interference pins, and that effects of interference pins on stress intensity factors are significant.
Computer generated isochromatic fringe patterns are given to verify photoelastic data.
