Abstract
A method for determining a shear elasticity and shear viscosity of a material based on resonance characteristics. A focused ultrasound wave is directed at the material to induce oscillations in the material, and a velocity of the material is measured. A spectrum of frequency of oscillation versus velocity is developed, and the resonance characteristics exhibited by the spectrum are used to estimate the shear elasticity and viscosity of the material.
