| Summary: | Development and the need of unification of fatigue life calculation methods of structural elements led to elaborate proper calculation procedures. The procedures were initially developed to apply in specialist areas of technique such as: aviation, ship building industry and power engineering. The attempt of elaboration of a universal procedure was released in 2006 and called FITNET.
In the paper there was performed an analysis of chosen problems connected with the fatigue life calculation procedure. A m exponent of a power applied in a description of fatigue life calculation and the fatigue limit were chosen for the analysis. The mentioned parameters essentially influence the description of a fatigue life curve that is a base for the fatigue life calculation method. The analysis of literature data was completed with own research results in the shape of fatigue life curves of chosen grades of steel and aluminum alloys. |
