| Abstract: | Low cycle fatigue (LCF) properties of steel BLY160 with low yield point ( LYP) was investigated. Low cycle fatigue tests were conducted on MTS809 electro-hydraulic servo fatigue testing machine. The tests were run under uniaxial tension-compression loading with total strain control. The response characteristics of cyclic stress, the relationship between cyclic stress and strain and the effects of amplitude and rate of strain on low cycle fatigue properties of the test material were researched under cyclic loading. The results show that BLY160 steel plate has excellent low cycle properties to meet the requirement for the steels for energy dissipation damper. |
| Keywords: | low yield point steel low cycle fatigue strain control strain amplitude strain rate |
