ULTRASONIC METHOD FOR QUANTIFYING THE NON-LINEAR ELASTICITY OF A MEDIUM USING SHEAR WAVES, AND DEVICE FOR IMPLEMENTING THIS METHOD

摘要

Ultrasonic method for quantifying the non-linear elasticity of a medium using shear waves, the method comprising the following steps: A1. - collecting a temporal succession of data on the elasticity of the medium using shear waves, 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 deformation variation, and B. - quantifying the non-linear elasticity of the medium depending on the temporal succession of data and the deformation variation.
