Kritéria multiaxiální únavy

Abstract

This thesis deals with the study of fatigue life prediction of materials at multiaxial fatigue. The first part of the thesis introduces uniaxial fatigue going to multiaxial fatigue. The next part focuses on the elaboration of separate criteria of multiaxial fatigue mainly for low-cycle fatigue for the estimation of life prediction of testing material. Because the testing samples were controlled strained at non-propositional low-cycle fatigue, this criteria was also selected in order to correspond with the given loading. The last part of this thesis is devoted to evaluation of individual tests from different loading paths in the half of the life prediction of the component and following evaluation using specific criteria.
