The Fatigue Damage Spectrum (FDS) is a popular method used in the industry to execute accelerated vibration testing for mechanical components and structures. This method uses acceleration test signals in time domain to derive vibrational velocity which in turn is used for obtaining induced mechanical stresses. Taking the SN-curve properties (slope and intercept) of the material and linear damage accumulation model (Palmgren/Miner) in account, the damage for the component is derived in frequency
