Fatigue Damage Spectrum for Reliability Test Compression - PowerPoint 

Vibration excitations of greatly different Peak Probability Distributions (PDFs) can produce identical PSDs and GRMS measurements. The Fatigue Damage Spectrum (FDS) will be shown to be a better represent the severity of the excitation when testing to fatigue.
