TL;DR: In this article, a beam element based on first-order shear deformation theory is developed to study the thermoelastic behavior of functionally graded beam structures, and the stiffness matrix has super-convergent property and the element is free of shear locking.

TL;DR: In this article, a spectral finite element method is employed to analyse the wave propagation behavior in a functionally graded (FG) beam subjected to high frequency impulse loading, which can be either thermal or mechanical.

TL;DR: In this paper, a theory of anisotropic and inhomogenous materials and solution techniques for wave propagation in one-dimensional and two-dimensional inhomogeneous materials is presented.

TL;DR: In this article, a locking free first-order shear deformable finite element is presented, and its utility in solving free vibration and wave propagation problems in laminated composite beam structures with symmetric and asymmetric ply stacking is demonstrated.

TL;DR: In this paper, a pseudospectral method for wave propagation analysis in anisotropic and inhomogeneous structures is presented. And the method is implemented in the same way as conventional finite element method and tested successfully on a variety of problems involving isotropic, orthotropic and functionally graded material structures.
