Abstract

In this study, a NURBS-based isogeometric approach is developed for transient analysis of laminated composite plates using the classical laminated plate theory (CLPT). Based on the isoparametric concept, the NURBS basis function is employed for both the parameterization of the geometry and the approximation of the plate deflection. An efficient and easy to implement technique is used for imposition of essential boundary conditions by simply fixing the deflection of the first row or first two rows of control points from the desired boundary for simply supported or clamped boundaries, respectively. Some numerical examples for transient response analysis of laminated plates with various boundary conditions under dynamic loadings are considered. The numerical results are obtained and compared with other available solutions in the literature. The comparisons demonstrate the efficiency and accuracy of the proposed approach for such problems.
