of J from certain formulae agree well with comphauce meas~ements for a round notched bar specimen subjected to tensile (Mode I) and torsional (Mode III) loadings. Crack growth resistance curves (R-curves) obtained by a three parameter technique are compared with those obtained by two current approaches. The .I,, values (Mode I) at initial crack growth are in good agreement with the Jinc values (Mode III). In addition, the effect of unloading on fracture toughness is examined.
