Abstract
AbstractThe dynamic response of the functionally graded material (FGM) plate under moving load considering the effect of temperature is investigated. The FGM plate properties are graded in the thickness direction based on the power-law distribution in terms. The Mindlin plate theory is employed to calculate the shear strain of the plate. The properties of the FGM plate such as the elastic modulus and coefficient of expansion due to effect of temperature are modeled. It is assumed that temperature variation is only in the direction of the plate thickness and that temperature field is assumed to be constant in the plane. Temperature distribution function along the plate thickness can be obtained by solving the governing equation of temperature transfer. Both mechanical strain and temperature-induced strain are employed to calculate the plate strain. Comparison study with previous results were performed to verify the effectiveness of the proposed model. Effects of temperature, moving load, plate thickness, and foundation parameters on the FGM plate are examined. It is found that they have a significant effect on the displacement of the plate. As to be expected, the plate displacement depends on the temperature, volume fraction index as well as velocity, and magnitude of moving load, being larger when they are larger.KeywordsFGMMEMTemperatureMoving load
