Bending, Buckling And Vibration Analysis Of FGM Thick Plates

Because of high application value in high-tech area(such as spaceflight, nuclear reactor, energy sources and power),FGM is widely used.So,the research about FGM considering shearing deformation is changing with each passing day .This paper ,which is based on three-dimensional elasticity mechanics and modeling by Ansys, is about bending ,buckling and vibration detailed analysis of FGM thick plates.Bending analysis about FGM thick plates: First, the shortage of the hypothesis and equation of classical plates theory is shown;give the hypothesis and equation of thick plates theory;deduce the essential equation and boundary conditions not only by broad sense remainder energy theorem,but also by three-dimensional elasticity mechanics.Then deduce the essential equation and boundary about FGM thick plates and predigest it.Buckling analysis about FGM thick plates: The development of the buckling research of FGM plates is introduced, deduce the buckling essential equation about FGM thick plates,.Expound the finite element method about elasticity buckle and the method about how to judge critical state.Then introduce the computing method of Ansys about buckling problem.Vibration analysis about FGM thick plates: The development of the vibration research of FGM plates is introduced. Deduce the dynamical essential equation thick plates of by three-dimensional elasticity mechanics boundary conditions. Deduce the dynamical essential equation of the FGM thick plates in the same way.Find bending ,buckling and vibration characteristic of FGM thick plates by detailed examples ,and obtain valuable conclusions . Modeling by Ansys is avoid complexity from computing by hand,and can be used in practical project after some modifications.
