    Fatigue crack initiation tests were carried out on notched specimens, with Kt values ranging from 1.4 to 4.2, made of a large variety of steels. The paper describes the application of the critical location approach to these tests on the basis of low-cycle fatigue data obtained on smooth specimens under Neuber control straining or under conventional reverse straining (Rε = (εminmax) = −1).
