Abstract
A unidirectional fiberglass epoxy composite is modelled as a homogeneous transversely isotropic continuum plate medium. Acousto-ultrasonic non-contact input-output characterization by tracing the stress waves (SH, P and SV waves) in the continuum is studied as if a transmitting and a receiving transducer were located on the same face of the plate but without direct contact.
The output displacements associated with each type of stress wave in the fiberglass epoxy composite are approximated by an asymptotic solution for an infinite transversely isotropic medium subjected to a harmonic point load. The polar diagrams for the amplitudes due to each type of stress wave in the plate are given.
