Nonlinear Dynamic and Vibration Analysis of an Eccentrically Stiffened E-FGM Plate in Thermal Environment
Abstract
This paper investigated the nonlinear dynamic and vibration of eccentrically stiffened functionally graded plates under temperature using an exponential distribution law (E-FGM). Both E-FGM plate and stiffeners are deformed under temperature. The formulations are based on the classical plate theory taking into account geometrical nonlinearity, initial geometrical imperfection, temperaturedependent properties and thermal stresses in both plates and stiffeners. By applying Galerkin method and using stress function, effects of geometrical properties, temperature and eccentrically stiffeners on the nonlinear dynamic and vibration of the eccentrically stiffened E-FGM plate in thermal environments are analyzed and discussed.
