Abstract

Potential use of acoustic microscopy at low frequency for determining elastic properties and characterizing internal defects have been recognized in the recent years. In this paper a theory is presented for the calculation of the acoustic material signature of an orthotropic half-space overlain by a fluid. The analysis is carried out for low frequency acoustic waves generated by a cylindrical transducer without a lens rod and the response is measured by a line receiver. Several new features of the material signature and their possible use in fiber reinforced composite material characterization are indicated.
