Abstract:Abstract. The Di erential Quadrature Method (DQM) is one of the most powerful approximation methods for analyzing the free vibration of rectangular plates. It is easy to use and straightforward to implement. However, in spite of its many advantages, the conventional DQM has some limitations in determining the natural frequencies of rectangular plates involving free corners. This is because it is very di cult to implement the free corner boundary condition in conventional DQM. As a result, the method may exhibi… Show more
