title = "The effect of loading history on unstable fracture of austenitic steel (304)",
abstract = "The present paper presents an analysis of the influence of loading history on unstable fracture of austenitic steel 304 (SS 304) using the J-integral and its applicability in situations where a loading history exists. A CT specimen is employed for the purpose. The loading history effect on the unstable fracture of SS 304 is studied by performing cyclic loading with different load histories at constant load range (ΔP i) and at constant stress intensity factor range (ΔK j). The results show that the plastic singularity is well described by the integral (J) for the different types of loadings used. Moreover, the real meaning of (J IC) as a representative of the maximum energy release rate is quite limited if it ignores the loading history. The experimental results show that the dissipated energy δJ is more active when the loading is done at constant δP. The evolution of δ J can be directly linked to the crack growth rate and to the extent of the plastic zone developed at the crack tip.",
