Abstract:

This patent application discloses a method to measure the complex frequency-dependent dilatational and shear wave numbers of a material under a static compressional force. The material is first vibrated in both vertical and horizontal directions while transfer functions are obtained in each direction. The two transfer functions are combined with a theoretical model to estimate a dilatational wave number and a shear wave number. The wave numbers can be utilized to give the complex dilatational wave speed, complex shear wave speed, complex Lame constants, complex Youngs modulus, complex shear modulus, and complex Poissons ratio.
