Abstract
In this article, thermoelastic wave propagation based on coupled thermoelasticity (without energy dissipation) in Green-Naghdi model is studied for functionally graded (FG) thick hollow cylinder. The meshless local Petrov-Galerkin method is developed to solve the boundary value problem. The Newmark finite difference method is used to treat the time dependence of the variables for transient problems. The mechanical properties of FG cylinder are assumed to vary across thickness of cylinder in terms of volume fraction as nonlinear function. A weak formulation for the set of governing equations is transformed into local integral equations on local subdomains by using a Heaviside test function. The propagation of thermal and elastic waves is discussed in details. The presented method shows high capability and efficiency for coupled thermoelasticity problems.
