The Spectral Analysis of Surface Waves (SASW) is a popular technique in seismics for imaging the ground subsurface. It uses the dispersive properties of Rayleigh waves in a transversely homogeneous, multilayered medium. The SASW approach is being transposed into the civil engineering domain to characterize subsurface damage in concrete structures. Such a damage consists in a few millimeters thick...
A new cellular model of the propagation of short ultrasonic waves in cancellous bone is introduced. The theoretical results derived from the proposed model have been compared with the well known macrocontinual Biot's theory. Independently, the experimental results obtained by the pulse transmission method for cancellous bovine bone and a model material have been reported. The data from time and frequency...
