Corner Cracks

Three-dimensional photoelasticity was used to measure mode I stress intensity factors of corner cracks in a double-shear bolted joint. A model of the joint assembly was manufactured from a photoelastic material and three different corner cracks were introduced using a cutting wheel. After the stress freezing process, slices along the crack fronts were cut and analyzed using three different photoelastic procedures. There was good correlation between the methods of analysis. Stress intensity factors of these cracks were found to vary along the crack front with a maximum at the bore of the hole and a minimum on the surface of the plate. This implies that the cracks are likely to grow more rapidly along the bore.

Exact Analytical Solutions

The application of the frozen stress photoelastic technique to the determination of stress intensity factors in two-and three-dimensional problems is discussed. The technique, involving casting flaws by the insertion of thin shims, is found to give accurate results for problems with a known exact analytical solutions: a central crack in a wide plate and an embedded circular crack. It is applied to other problems without a known solution or for which only approximate solutions, often providing inconsistent answers exist.
