Study of the effects of elastic unloadings on the J/sub I/-R curves from compact specimens
An investigation was performed to evaluate the effects of elastic unloadings on the J-Integral Resistance Curves of ASTM A106 Class C steel and 3-Ni Steel. Compact specimens (1T) were tested using a multi-specimen technique, direct current potential drop technique and the elastic unloading compliance technique with unloadings ranging from 10 to 90%. The two former techniques were 0% unloading procedures used to generate the reference J-R curves for comparison to the elastic unloading J-R curves for the two steels. The results of the investigations of these materials indicate that there was no significant difference in the J-R curves that resulted from the elastic unloading compliance technique.
