摘要：

A new criterion is proposed for evaluating the multiaxial high-cycle fatigue limit of components with notches and superficial small holes. Two parameters are specified: (1) one governing crack initiation and (2) the other governing initial crack growth. The new criterion is based on the multiaxial fatigue criterion for smooth components previously proposed by the authors. The accuracies of the proposed and conventional criteria are evaluated using experimentally determined fatigue limit data of notches and superficial small holes under combined bending and torsion stresses and combined axial and torsion stresses. The error of the proposed criterion is approximately 10%. (C) 2014 Elsevier Ltd. All rights reserved.
