Abstract: An ultrasonic method for quantifying the nonlinear shear wave elasticity of a medium, the method comprising the following steps: A1.—collecting a temporal succession of shear wave elasticity data from the medium, A2.—applying, to the medium, a deformation that successively changes according to a predetermined sequence of deformations, during the collection of the shear waves, A3.—observing the actual evolution of deformation, and B.—quantifying the nonlinear elasticity of the medium depending on the temporal succession of data and the evolution of deformation.
