Abstract
AbstractA new discrete singular convolution (DSC) method is developed for vibration, buckling and static analyses of arbitrary straight‐sided quadrilateral plates. The straight‐sided quadrilateral domain is mapped into a square domain in the computational space using a four‐node element. By using the geometric transformation, the governing equations and boundary conditions of the plate are transformed from the physical domain into a square computational domain. Numerical examples illustrating the accuracy and convergence of the DSC method for straight‐sided quadrilateral thin plates such as rectangular, skew, trapezoidal and rhombic plates are presented. The results obtained by the DSC method were compared with those obtained by the other numerical and analytical methods. Copyright © 2007 John Wiley & Sons, Ltd.
