tailieunhanh - Nonlinear vibration of porous funcationally graded cylindrical panel using reddy’s high order shear deformation

The study results for dynamic response of PFGCP present the effect of geometrical ratio, elastic foundations: Winkler foundation and Paskternak foundation; loads: mechanical load and thermal load; and the material properties and distribution type of porosity. The results are shown numerically and are determined by using Galerkin methods and Fourth-order Runge-Kutta method. | VNU Journal of Science Mathematics Physics Vol. 35 No. 4 2019 1-21 Original Article Nonlinear Vibration of Porous Funcationally Graded Cylindrical Panel Using Reddy s High Order Shear Deformation Vu Minh Anh1 Nguyen Dinh Duc1 2 1 Department of Construction and Transportation Engineering VNU University of Engineering and Technology 144 Xuan Thuy Cau Giay Hanoi Vietnam 2 Infrastructure Engineering Program VNU Vietnam-Japan University VJU My Dinh 1 Tu Liem Hanoi Vietnam Received 02 December 2019 Accepted 06 December 2019 Abstract The nonlinear dynamic response and vibration of porous functionally graded cylindrical panel PFGCP subjected to the thermal load mechanical load and resting on elastic foundations are determined by an analytical approach as the Reddy s third order shear deformation theory Ahry s function The study results for dynamic response of PFGCP present the effect of geometrical ratio elastic foundations Winkler foundation and Paskternak foundation loads mechanical load and thermal load and the material properties and distribution type of porosity.

Introduction With the requirements of working ability such as bearing high temperature in the harsh environment of some key industries such as defense industries aircraft space vehicles reactor vessels and other engineering structures in the world many advanced materials have appeared including Functionally Graded Materials FGMs . FGMs is a composites material and is made by a combination of two main materials metal and ceramic. Therefore the material properties of FGMs will have all the ________ Corresponding author.
