Wave Propagation Fiber Reinforced Materials.

Abstract

This paper discusses the propagation of elastic waves in materials reinforced by inextensible fibers. Slowness surfaces, energy fluxes and directions of propagation are determined and expressed in terms of material properties and fiber directions. The case of two domains of fiber-reinforced materials, similar in all respects except for fiber direction, and bonded together at a plane interface, is considered in detail. The misalignment in fiber directions that occurs at the bonded interface is shown to cause a significant scattering of mechanical energy. The range of validity of the mathematical model employed in this paper is indicated, and it is shown that the results may be useful in practical cases. The existance of surface waves is also discussed. (Author, modified-PL)
