CONSIDERATIONS REGARDING THE NECESSITY OF
FATIGUE APPROACH ON DIFFERENT SCALES.
FATIGUE MESOSCOPIC (III)
An extensive literature review is presented in this paper, composed of
several parts, regarding the present-day topic of mesoscopic fatigue of
materials. This subject is scarcely represented in the literature from our country.
The authors present a short and accessible approach in order to
familiarize research and production engineers with the new aspects of fatigue
calculation based on the transition from macro to meso scale. Mesoscopic
fatigue takes into account the material’s behavior at the level of crystal grains.
