Abstract
Two techniques, speckle photography and holographic interferometry, are used to test three-dimensional finite elements calculations in an internally pressurized cylinder with an external part-circular crack. Opening displacements along the crack line are measured by speckle photography and radial displacements are obtained from holographic fringe patterns. Good agreement between experimental and numerical data is obtained. Stress-intensity factor variations along the crack front are calculated from numerical results.
