Abstract

Using principles of Statistical Energy Analysis, a nondestructive evaluation methodology is presented to estimate the average Poisson's ratio and the average dynamic complex bulk, shear, extensional, and longitudinal moduli of dimension stone. The estimated moduli represent an average over the volume of the test specimen and over a frequency band up to 200 kHz. The proposed methodology is based upon the energy-density decay function of an impact-generated diffuse wave field using small dynamic strain amplitudes. Invoking the principles of linear viscoelasticity, various loss parameters are also extracted and discussed. The methodology allows the evaluation of the energy dissipation characteristics of different stone types, and their dependence upon the stone microstructure.
