Shock Response Spectra:Uses and Abuses


The Shock Response Spectrum (SRS) is the most frequently used method to characterize shock despite its limitations. The course will discuss the variations of SRS, pseudo-velocity SRS, methods to compute SRS, SRS of several classical waveforms, advantages and disadvantages, SRS flaws, SRS uses, and shock testing on shakers that use SRS.
