      One cannot generate a Frequency Response (i.e., Bode) plot for von Mises stress in a harmonic analysis as it is not a harmonic result. It is periodic, but it is not harmonic. The same is true of Total Deformation (or, indeed, any derived quantity). The component values are harmonic, but values derived from them are not. One can use the amplitude of the equivalent stress.
