Influence of temperature on material data determined on the base of low cycle fatigue tests

The work deals with the method of fatigue life calculations with application of material characteristics determined during low cycle fatigue tests [7]. Analysis of obtained results enables to state that values of parameters n’ and K’ change and depend on fatigue life period n/N as well as temperature. Values of parameters n’ and K’ determined in half of fatigue life (n/N=0,5) are nor mean values for the whole range of fatigue life. The comparative analysis of obtained results indicates the scale of simplification by assumption, as results of elaboration, of values of parameters n’ and K’ from the one period of fatigue life n/N=0,5.
