A procedure for CTOD calculation under slow stable crack growth conditions is presented in this work. This procedure gives more accurate CTOD values than those obtained using existing standards, and can be used in tests in which the slow stable crack growth is measured. An analysis of the errors made, when the traditional ([I], ASTM STP 668, pp. 307‐333) or the European Group of Fracture equations are used, is also made. A weighting factor on Δ a is proposed for tests without crack growth measurement.
