| Abstract: | Discrete singular convolution (DSC) is a novel and potential computational method in recent years. The method is simple and reliable. It is successfully utilized for analyzing structural components. In this paper,the principle of the DSC is introduced firstly.Then, the DSC is used for solving two classes of problems: the bending of the beam and the free vibration of rectangular plates with three different boundary conditions. Compared with the data obtained by using the differential quadrature method(DQM), results show that the DSC is a simple and reliable numericaI method. |
