WebAt quasi-static strain rates, the waves are allowed enough time to come to equilibrium as the load is increased; whereas at dynamic strain rates, the stress waves are detectable and not constant through the material. At high strain rates, these waves have a low wavelength. As the strain rate is decreased, the waves become longer.
