This method consists in generating <i>P-v</i> curves of the "<i>a constant</i>" type, and obtain their intercepts with the experimental curve. By using <i>P-v-a</i> data of an A 508 C(T) specimen, and a two-dimensional finite element model, it is shown that the method contributes to generate relevant data concerning the evolution of the crack size in a test. The results obtained with the method make it possible to construct a <i>J-R</i> curve which is practically identical to that constructed with the original experimental data.}, number={5}, journal={Revista de Metalurgia}, author={Donoso, J.
