  • Title: [Interpretation of mechanical impedance of biological tissues in the three level model with the power source of vibrations].
    Author: Timanin EM, Eremin EV.
    Journal: Biofizika; 2003; 48(2):324-31. PubMed ID: 12723359.
    Abstract:
    Theoretical expressions were derived for the mechanical impedance of a round piston on the surface of a viscoelastic triple layer with sublayers linked with each other and with the rigid base. The expressions were obtained on the assumption that the piston creates an even oscillatory pressure and does not create shear stresses. The calculations in the developed model were compared with corresponding calculations in the known strict model and with experimental values obtained on a relaxed and stressed human biceps. The results obtained suggest that models of this kind can be used for reconstructing the mechanical parameters of multilayer biological tissues.
