Abstract

A system and method for measuring one or more viscoelastic properties of a material under measurement is disclosed. The system includes an emitter-observer transducer pair separated by the material. A signal processing assembly is operable to (i) apply a plurality of excitation signals to the emitter transducer, wherein each of the excitation signals comprises a continuous-wave sinusoidal waveform, (ii) record a plurality of output signals at the observer transducer, wherein each of the output signals corresponds to one of the excitation signals, (iii) analyze the output signals to measure the sound speed of the material, and (iv) determine the viscoelastic properties of the material under measurement by optimizing the parameters of an infinite echo model. The system provides a non-destructive approach for in-situ measurement of viscoelastic material properties.
