| Popis: |
The present paper deals with cyclic properties and hysteresis energy accumulation occurring in fatigue tested sintered steels. The specimens were subjected to sinusoidal uniaxial tension-compression (R = -1) within a wide range of LCF/HCF loading up to the fatigue limit. In each test determined were successively: plastic deformation e p , hysteresis energy ΔW and total energy W accumulated throughout the process. A new method was applied to determine e p , ΔW and W. The experimental results served a basis for verifying the models of plastic strain e p , energy ΔW and W. |
