The general problem of thermoelastic waves in anisotropic periodically laminated composites

Abstract

The propagation of harmonic waves in a laminated composite consisting of an arbitrary number of layered anisotropic plates is studied. In the context of the generalized theory of thermoelasticity, each layer is allowed to have a monoclinic degree of symmetry in the thermoelastic sense. Waves are allowed to propagate along any angle from the normal to the plates, as well as along any azimuthal angle. The problem is treated analytically using a combination of linear orthogonal transformations and the transfer matrix method to reach the characteristic equation of the composite. Numerical illustrations are given in the form of dispersion and attenuation curves of different representative layering.
