Title: Innovative Capability to Quantify Fatigue Damage and Assessment of Endurance Limit in Spectrum Load Histories
Agency: DOD
Contract: N68335-11-C-0054
Award Amount: $149,192.00
 

Abstract:

Develop analytical and empirical formulations based on critical test data for reliable fatigue and crack growth life predictions of long spectrum histories involving high frequency small amplitude vibratory loading cycles. Extend these formulations to account for surface conditions, treatments and finishes, and residual stresses. Incorporate these analytical formulations in Navy programs such as FAMS, FASTRAN, and UNIGROW for reliable fatigue and crack life predictions. Investigate improvements to existing voice-coil servo-hydraulic technology and other alternative accelerated fatigue test techniques for application to spectrum loading with high-frequency content on commonly used test laboratory specimens. Develop necessary software and hardware for improved fatigue testing at high frequencies involving servo-valve and other technologies by closely working with a test machine manufacturer.
