Variational Solution and Numerical Simulation of Bimodular Functionally Graded Thin Circular Plates under Large Deformation

In this study, the variational method and numerical simulation technique were used to solve problem of bimodular functionally graded thin plates under large deformation. During application method, functional was established on elastic strain energy plate while variation in realized by changing undetermined coefficients functional. As a result, classical Ritz adopted obtain important relationship between load maximum deflection that is great concern engineering design. At same time, also utilized applying software ABAQUS6.14.4, which effect properties materials simulated subareas tension compression, as well layering along direction thickness, respectively. This study indicates results agree with those from solution, comparing plate, verifies validity solution obtained. The presented are helpful for refined analysis optimization design flexible structures, composed materials, structure
