Three experimental techniques for developing the crack resistance curve and plane stress fracture toughness using center cracked panels are reviewed. One technique involving a plasticity characterization based on the crack opening stretch is discussed in detail.
Experimental data for a variety of materials and thicknesses are presented which show the equivalence of the various methods for determining the crack resistance curve.
