Fatigue properties of notched specimens made of FeP04 steel
Fatigue properties of the specimens with different notches made of FeP04 steel are presented. The specimens ware characterized by double symmetric lateral notches with a notch root radius ranging from ρ = 0.2 to 10 mm. The MTS 809 servo-hydraulic device was used for tests. All fatigue tests were per...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Fatigue properties of the specimens with different notches made of FeP04 steel are presented. The specimens ware characterized by double symmetric lateral notches with a notch root radius ranging from ρ = 0.2 to 10 mm. The MTS 809 servo-hydraulic device was used for tests. All fatigue tests were performed under force control, by imposing a constant value of the nominal load ratio (R = 0) and a load amplitude Pa = 6 kN for the notch root ρ = 0.2 mm and 7 kN for the notch root ρ = 1.25; 2.5 and 10 mm. The test frequency varied from 13 and 15 Hz. During the tests under constant load fatigue weakening of the material and an increase in strain were observed. |
