Technique used in dynamic mechanical analysis in which a specimen is subjected to the superposition of a number of forced sinusoidal oscillations of different frequencies.
Note: In one experiment, this technique delivers the frequency dependence of the mechanical properties at all the frequencies covered by the forced sinusoidal oscillations.
