| Abstract | A method of characterizing viscoelastic properties of a sample of a substance, includes the application (52) to the sample of an oscillatory mechanical excitation, the measurement (54) of a response of the sample to the mechanical excitation and the determination (56, 58) of characteristic parameters of the viscoelastic properties of the sample, is characterized in that the determination (56, 58) of characteristic parameters includes the steps of expressing the response in the form of a nonlinear periodic response signal, of general form x(t)=x0+x1 cos(phi(t)-rho0), where phi(t) is the phase of the signal, and of determining viscoelasticity parameters, characterizing the nonlinearity of the response signal. |
