Static and Dynamic Analyses of Thick Laminated Composite Foundation Plates
GAO Rong-yu
Abstract：Based on dynamic equilibrium equations of three-dimensional elasticity, a state equation was established for orthotropic foundation plates using double Fourier series, in which no assumption about stress or displacement modes was made. Analytical solutions and frequency equations of unified formulas were presented for thin and thick laminated foundation plates. Nine elastic constants are included in these solutions, furthermore, continuous conditions between players can be satisfied. All the displacements, stress components, foundation reactions and vibrant frequencies can be obtained. Numerical results show that this method has a high efficiency and accuracy but a little amount of calculation work, so it is convenient for parameter input and output.
