Description

Various ultrasonic methods[1–3] have been proposed for determination of anisotropic elastic stiffness and constants of composite materials. Among them, the double through transmission method[2] is effective because of direct measurement of the phase velocity as well as simple experimental set-up of use of single transducer. However, this method requires to install a reflector plate in the opposite side of the transducer. For determining anisotropic elastic properties of fabricated structural parts, which have different shape from flat panels, however, the application of the double transmission method is difficult.
