“…Subsurface waves have been successfully reported for example, in residual stress measurements in rails by Brokowski and Deputat [I21 and explained by Nikiforov and Charitonov [13]. Surface waves are emphasized in the present paper and another paper written by Rose et al [14]. Similar results on surface waves for off-diagonal terms of stiffness matrix determinations have recently been introduced by Bucur and Rocaboy [151.…”

“…For a particular measurement protocol with a fixed gate and recording threshold, the presence of a gross defect or a crack will lead to a bizarre result for the wave velocity measurements and hence for some specific elastic constants. This will point out a warning to discard any further computations or to proceed with a standard normal beam pulse echo C scan kind of test or even a dual transducer oblique incidence kind of test before proceeding [14].…”

A surface wave velocity measurement technique is used to supply supporting measurements in the computation of elastic constants for practical nondestructive evaluation of composite materials. Theoretical modeling work is carried out to illustrate the surface wave velocity changes as a function of angle with respect to the axes along the fibers of a unidirectional graphite epoxy composite material for a variety of different problems, including porosity (PC) changes, fiber volume fraction (FF) changes, and delamination. Experiments are conducted on two unidirectional reinforced composites and a (O-90), cross ply graphite epoxy laminate to illustrate the surface wave velocity measurements and the inverse computation procedure for evaluation of the stiffness coefficients. Variations of the feature values in the stiffness matrix are also discussed for inhomogeneities, delaminations through cracking, and large defects.

“…However, tomography using these ultrasonic waves is not widely utilized in NDE. Rose et al (1988) discussed the technique for mapping out interfacial weakness in an adhesive bond structure using plate leaky wave amplitude. Lamb waves along the ray paths were used without the tomographic technique in their work.…”

This work shows that it is possible to obtain information about more than one parameter from acoustic field information. A variety of ultrasonic Lamb wave modes were utilized to reconstruct thickness and density of an isotropic plate. An image reconstruction of one parameter (thickness of a plate) was carried out for four cases, i.e., the lowest symmetrical and antisymmetrical modes, and the fastest symmetrical and anti symmetrical Lamb waves among multiple modes. For two parameter reconstructions (thickness and density), the image processing was performed using the lowest symmetrical and anti symmetrical modes simultaneously. In this work, a modified version of algebraic reconstruction technique (ART), which is a form of finite-series expansion method, was employed to reconstruct the ultrasonically computed tomographic images. Results from several sample geometries are presented.
