Free Vibration of Functionally Graded Skew Plates Subjected to Thermal Environment

Abstract

Here, the free vibration behavior of functionally graded skew plates is investigated using finite element procedure. Temperature field is assumed to be a uniform distribution over the plate surface and varied in thickness direction only. Material properties are assumed to be temperature dependent and graded in the thickness direction according to simple power law distribution. For the numerical illustrations, silicon nitride/stainless steel is considered as functionally graded material. The variation in frequencies is highlighted considering gradient index, temperature, thickness and aspect ratios, and skew angle of the plate.
