SCATTERING OF ACOUSTIC BEAMS BY CRACKED COMPOSITES

An analytical technique is developed to compute the surface response of a cracked composite half-space when it is excited by a bounded acoustic beam. The numerical computations show that an internal crack strongly affects the surface response of a cracked composite half-space. It has been found that very small cracks can also be detected by striking the composite with an acoustic beam as long as the crack length is relatively large compared to the elastic wave length in the solid. Other study findings are also discussed.
