The non-proportionality of the state of stress resulted from a phase shift of the value delta = 90° of load components with sine signals and variable ratio of shear to normal stress lambda. On the basis of the results, Wöhler's curves were prepared, presenting the dependency of fatigue life to equivalent stress levels. Their analysis shows that fatigue life is strictly connected with the value of coefficient lambda. The existence of its critical value can also be observed, which results in the highest fatigue life reduction. The value is different for each material. Furthermore, fractographic tests were conducted showing the influence of the level and type of load on the fracture face"},{"@xml:lang":"sl","#text":"Članek analizira vpliv razmerja med strižnimi in normalnimi napetostmi v pogojih večosnih utrujenostnih obremenitev na utrujenostno trajnostno dobo, morfologijo površine utrujenostnega loma in orientacijo ravnine razpoke.
