Niskocyklowa trwałość zmęczeniowa stali o podwyższonej wytrzymałości w ujęciu energetycznym

Czesław Goss

In the paper diagrams and analytical dependences have been given for determination of low-cycle fatigue from energy considerations. In this way Manson-Coffin equation and formulae for constant coeficients given therein were obtained. Analysis has been performed by means of energy criteria of fatigue life. From these considerations it has been proposed a new criterion based on the difference betwen cumulative dissipation of energy obtained from experiments and from area measurements of hysteresis loops, the latter being obtained by scale transformation method.
