method has recently been developed for determining a nonlinear fracture toughness parameter defined by the relation where G, is the critical elastic strain energy rate as defined by Irwin. The C term is a function of the nonlinearity of the load-displacement test record and has been evaluated using
J-integral resistance curves for three specimen thicknesses and valid (according to ASTM Method E 399) K~ values at 76 K are reported for aluminum alloy 2219. The J-integral values were independent of thickness at small crack extensions, but at substantial crack extensions the values for the thin sp
