Proposition of Low-Cycle Fatigue Test Termination Criterion Based on Specimen Temperature Change

Abstract:

This paper presents proposition of the low-cycle fatigue test termination criterion based on specimen temperature change. The tests were performed using specimens made of G-X12CrMoVNbN9-1 (GP91) martensitic cast steel under axial tension-compression conditions with strain controlled at the total strain amplitude levels amounting to ε_ac = 0.25%, 0.5% and 0.6%. Very good compliance of the proposed criterion with the criterion used so far was obtained. The discrepancy for the tested material has not exceeded 2% in the ε_ac stress range not exceeding 0.5%.
