    abstract = {The Fatigue Damage Spectrum (FDS) is the state-of-the-art method when it comes to industrial practices regarding accelerated fatigue testing of components. This process promises test acceleration while maintaining identical damage and frequency content as those experienced in actual service conditions. The research work focuses on some of the assumptions used in the process of FDS. The first being, proportionality of mechanical stress and vibrational velocity and the second being the effect of the material parameters like the slope of SN-Curve.
The proportionality of mechanical stress and a vibrational parameter have been investigated in this study experimentally. Both the parameters vibrational velocity and acceleration are considered. The results are intended to assist the user in choosing a vibrational parameter which will cover the real mechanical stresses specific to the application case. The selection of material parameter for FDS affects the results of test acceleration. Here, material parameters like slope of SN-Curve from standards as well as from an experimentally determined SN-Curve are employed to highlight the effects. All tests are conducted on generic specimens of steel and copper using an electrodynamic shaker under laboratory conditions. The ultimate aim of the study is to scrutinize different aspects of FDS in order to unveil further prospects of this method.},
