In the present study, Discrete Singular Convolution (DSC) method is developed for free
vibration analysis of plates and membranes with trapezoidal shape. The straight-sided
quadrilateral domain is mapped into a square domain in the computational space using a fournode
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 ofthe DSC method for
trapezoidal plates and membranes are presented. The results obtained by DSC method were
compared with those obtained by the other numerical and analytical methods.
