Abstract
This paper shows that fatigue limit 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 fatigue limit criterion considered is the Dang Van one. Fatigue tests (tension-compression, bending and torsion) carried out by the Cetim, are used to calibrate the critical volume.
