Static and Dynamic analysis of Functionally Graded Flat Panels

Majhi , Bikash Kumar (2013) Static and Dynamic analysis of Functionally Graded Flat Panels. BTech thesis.



Functionally graded materials have received a lot of interest in recent days by their diversified and potential applications in aerospace and other industries. They have high specific mechanical properties and high temperature capabilities which makes them special over all the exiting advanced materials. The present work investigated static and dynamic analysis of functionally graded plate. The material properties vary continuously from metal (bottom surface) to ceramic (top surface). The effective material properties of functionally graded materials for the plate structures are assumed to be temperature independent and graded in the plate thickness direction according to a power law distribution of the volume fractions of the constituents. The present model is developed using ANSYS parametric design language code in the ANSYS platform. An eight noded isoparametric quadrilateral shell element is used to discretise the present model for both static as well as dynamic analysis. A convergence test has been done with different mesh refinement and compared with published results. The parametric study indicates that the power-law indices, thickness ratios, aspect ratios, support conditions and different material properties have significant effect on non-dimensional mid-point deflection.
