文摘
A novel vibration-based fatigue experiment is built to study the fatigue properties of Ti-6Al-4V annular discs. Nonlinear vibration characteristics of the disc are clarified for the fatigue test. High-cycle fatigue properties of the discs and the corresponding segments are obtained. Fatigue limit stress of the discs can be predicted well by the proposed elliptic multiaxial fatigue criterion.
