True and Nominal Stress during Low Cycle Fatigue Tests of Metals

Abstract:

In this paper results of P91 cast steel after static and fatigue tests were presented. During the tests longitudinal and transverse strains of the specimen were measured. Basing on the results a comparative analysis of nominal stresses σ_n, true stresses σ_rz, nominal strain energy ΔW_{pl (n)} and true strain energy ΔW_{pl (n)} was carried out. It was stated that differences between determined paramters rise with increasing strain.
