Summary: | 碩士 === 國立成功大學 === 工程科學系碩博士班 === 93 === This study presents natural frequencies of rectangular plate with single-layered、two-layered and partial two-layered in the central part by Finite Element Method.
Based on Mindlin’s plate theory, the displacements, strains and stresses of single-layered rectangular plate can be defined to calculate strain energy and kinetic energy. The displacements solved from static equilibrium equations are used as shape functions of one element. Then, the Finite Element Method is employed to obtain the natural frequencies of the entire plate. The effects of thickness and element number on the natural frequencies of the plate are studied.
Furthermore, the displacements of two-layered rectangular plate are defined. The natural frequencies of rectangular composite plate with two-layered or partial two-layered in the central also are studied by FEM.
