Abstract
This paper utilizes the Stroh-Barnett's integral formalism of surface waves in anisotropic solids to calculate the variation of surface wave speeds of a unidirectional fibre-reinforced composite in an efficient way. The decaying pattenr of the displacements and tractions along the depth were also calculated using the determined surface wave speeds. To study the propagations of surface waves in the fibre-reinforced composite plate experimentally, point-source/point-receiver (PS/PR) experiments were conducted. A pulsed laser was utilized to generate a point disturbance in the composite plate and the transient waves were recorded by a PZT transducer with an acting diameter of about 1.5 mm. The slowness curves of the surface wave energy velocity were determined from the experimental data and the results were in accordance with those calculated theoretically. © 1994.
