Photoelastic determination of stress intensity factors for single and interacting cracks and comparison with calculated results. Part II: Three-dimensional problems
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.
