Experimentally Determined Shape Factors for Deep Part-Through Cracks in a Thick-Walled Pressure Vessel

Source

Fracture mechanics shape factors for deep, part-through cracks in thick-walled epoxy pressure vessel were determined experimentally and compared with three theoretical estimates. The agreement was especially good for cracks of depth approximately equal to half the wall thickness. The fracture toughness, KIc, of the epoxy was measured with ½-in. square beams loaded in four-point bending and was found to be 929 psi in.
