Abstract
Sentient will develop enhanced fretting fatigue analysis software with rigorous consideration of surface roughness effects in the stick/slip phenomena and fatigue. This will be coupled with an analysis of the stresses and resulting degradation in the material. Sentient will utilize diagnostic data in the form of vibration measurements and/or measured shaft torque to determine the loading conditions and damage progression at the contact. This technology will provide advanced remaining useful life estimates for spline shaft for rotorcraft and other applications.
