摘要：
Tests have been carried out on smooth and notched specimens submitted to cyclic combined loading. The role of the hydrostatic pressure has been clarified using a volumetric approach. The average hydrostatic pressure and the shear stress have been computed in the fatigue process volume. An elliptical dependence between the effective shear stress and the hydrostatic pressure has been shown. (C) 2001 Elsevier Science Ltd. All rights reserved.
