Abstract

Functionally graded materials (FGMs) are advanced composites whose properties are continuously variable according to their dimensions in one or more predefined directions. The application range of this material is becoming wider and wider, therefore, studies on the activity of functionally graded materials (FGMs) in high-temperature environments become more and more important and necessary. In this study, a mesh-free Radial Point Interpolation Method (RPIM) has been proposed to solve a coupled thermo-mechanical problem in functionally graded metal/ceramic plates. The most important advantage of this method is that the shape functions satisfy the property of Kronecker's delta function. Thus the essential boundary conditions are easily implemented as in the finite element method (FEM). The obtained results are compared with the reference ones from analytical solutions and finite element methods by commercial software COMSOL Multiphysics to verify the effectiveness and reliability of this method.
