Abstract
The purpose of the research is searching for ways preliminary revealing the moment of macrocracks origination while testing samples and details for fatigue limit with the help of asymmetry of oscillation cycles, at an appropriate excitation duty, exceeding in accuracy the failure criterion being used nowadays.

Résumé
Le but du travail est de trouver les phénomènes précurseurs des microfissures de fatigue par une méthode utilisant des cycles d'oscillation assymétriques, dans un régime excitation excédant les critères de destruction actuellement utilisés.
