Abstract : An experimental determination of the stress intensity around surface flaws in hollow cylinders is presented. The photoelastic stress freezing and slicing method was used to determine the stress intensity factor at various points around the circular edge of a surface flaw embedded in a hollow cylinder subjected to bending loads. The effect of the flaw depth to wall thickness ratio is included in this work. Data from 11 different geometries are presented. The effects of a change in the radius of the surface flaw or the cylindrical wall thickness are investigated separately for constant penetration depth to wall thickness ratios. (Author)
