Abstract:
This work aims to introduce a multiaxial fatigue criterion for hard metals. The model is based on the definition of a fatigue damage operator, which contains information on the fatigue solicitation provided by the stress history. Numerical aspects associated with the determination of such fatigue damage operator are presented. An assessment of the proposed fatigue model shows that the predictions obtained are in good agreement with experimental results published in the literature for a number of different materials.
