A simple and accurate mixed Ritz-DQM formulation for free vibration of rectangular plates involving free corners
It is well known that the classical global approximation methods such as the conventional Ritz method and the conventional differential quadrature method (DQM) have some difficulty in determining the natural frequencies of rectangular plates involving free corners. The mixed Ritz-DQM formulation, wh...
