On the Accuracy and Stability of a Variety of Differential Quadrature Formulations for the Vibration Analysis of Beams

The occurrence of spurious complex eigenvalues is a serious stability problem in many differential quadrature methods (DQMs). This paper studies the accuracy and stability of a variety of different differential quadrature formulations. Special emphasis is given to two local DQMs. One utilizes both f...
