Abstract
Free vibration analysis of skew and rhombic membranes is presented. In the proposed approach, irregular physical domain is transformed into a rectangular domain by using geometric coordinate transformation. Four-node element is used for geometric mapping. For demonstration of the accuracy and convergence of the method, some numerical examples are provided. The results obtained by the DSC method are compared with those obtained by other numerical and analytical methods. (C) 2008 Elsevier B.V. All rights reserved.
