Abstract
The measurement of J-resistence curves and their proof values at crack initiations are carried out with the method of three curves from a single specimen by using 12CrlMoV, 1.25Cr0. 5MoSi, 16MnR steels and two weld metals. The results of the single specimen are in agreement with those of the standard multi-specimen method. It shows from the experiments that the connected analyses of the three curves from a single specimen are in accordance with the physical fracture processes of precracked three point bending specimens. The ductile crack extension of the materials tested follows the power law relation.
