Fatigue Design of Notched Components with Stress Gradients and Cyclic Plasticity

Abstract

This paper shows that fatigue strength of notched specimens under cyclic loading can be simply and accurately estimated by using elastic-plastic computations and averaging stress over a critical volume obtained by an optimisation process minimizing the dispersion between experiments and simulations. The Dang Van high cycle fatigue criterion is considered. Fatigue tests (tension-compression, bending and torsion) carried out by the Cetim, are used to calibrate the critical volume.
