Triangular Differential Quadrature Method in Bending Analysis of Triangular Symmetric Laminated Plates

The main advantage of triangular differential quadrature method in numerical simulations of problems in triangular domain is that it needs very few grid points compared to those of low order methods. In the current work, the method is implemented to analyze the bending behavior of relatively thick triangular composite plates based on the concept of first-order shear deformation theory. A set of triangular symmetric laminated plates with various lay-ups, length to thickness ratios, and boundary conditions is considered. The results are discussed in detail and compared with those obtained from finite element method of analysis using ANSYS package.
