In this work, the fatigue behaviour of 316 stainless steel is studied with different critical plane models. Seven cylindrical samples were used for study, being subjected to complex loading paths, generating combined stresses along axial and transversal sample directions, these being: individual stress, hoop alternating a proportional combination non-proportional L-shaped square-shaped stress. ...

This article studies the retardation effect in plasticity-induced fatigue crack growth rate for a low-medium strength steel, due to appearance of microdeflections path. To this end, finite element method was used model with its kinked tip under several stress intensity factor (SIF) ranges. The results allowed calculation (after small number cycles) propagation multiaxial and uniaxial configurat...
