Linear Static And Vibration Analysis Of Circular And Annular Plates By The Harmonic Differential Quadrature (HDQ) Method
Öz
Numerical solution to static and free vibration analysis of thin circular and annular plates having various supports and load conditions are obtained by the method of Harmonic Differential Quadrature (HDQ). Bending moments, normal stress, and deflections of circular plate are found for uniformly distributed, central concentrated, and non-uniformly loads. Both clamped and simply supported edges are considered as boundary conditions. Results are obtained by using various number of grid points. The obtained results are compared with existing solutions available from other numerical methods and analytical results. The method presented gives efficient accurate results for the deflection and bending analysis of circular plates.
