Influence of FGM on the Parametric Instability of Skew Plates in Thermal Environment

The present work explains the influence of functionally graded material on parametric instability of skew plate in high thermal environments subjected to periodic loads. The graded material properties and temperature distribution are varied using power law. The basic kinematics of third-order shear deformation hypothesis is adopted to analyze the plate to be established in a finite element using quadrangular elements and these are updated into skew plate geometry by applying an appropriate transformation rule. A four-noded rectangular element is employed to create the work for finite element study of the instability regions of the skew plate in the parametric space by using Bolton’s approach. Difference between the results of the current numerical solution for finite element approach and the results of literature are plotted. The effects of temperature difference, index of power law, and skew angle of FGM plate parametric instability discussed in detail.
