Abstract
AbstractThe article is concerned with the motion of Lamb-type guided waves in a unidirectional fiber-reinforced composite under ultrasonic sources. This kind of composite is much stiffer along its axis than across its transverse direction and therefore shows orthotropic material properties. The dispersion relation of free guided waves propagating in a unidirectional composite plate is derived that results in dispersion curves. Using reciprocity in elastodynamics, closed-form solutions of elastic wave motions subjected to time-harmonic loads in a unidirectional fiber-reinforced composite are in a simple manner computed. The obtained computations can be very useful for developing ultrasound-based methods for nondestructive evaluation of composite structures.
