RESPONSE OF FUNCTIONALLY GRADED BEAMS OF DIFFERENT MATERIAL COMBINATIONS UNDER THERMAL ENVIRONMENT

In the present work, static and free vibration response of functionally graded beam is investigated under thermal environment using Finite Element method (FEM). The functionally graded (FG) material beam is considered to be composed of various material combinations like metal/metal, metal/ceramic and ceramic/ceramic. The material properties of the beam are assumed to be graded in the thickness direction according to a simple power law distribution. The deflection and mode shapes of the FG beams are obtained for Clamped-Free, Clamped-Clamped and Simply Supported boundary conditions under both mechanical and thermal load. Numerical results are obtained for the model in ANSYS software to show the influence of grading of materials, material constituents, boundary conditions, volume fraction and temperature conditions on the response of the FG beams
