Static and transient analysis of sandwich composite plates using isogeometric analysis.

In this work, an effective numerical approach based on the isogeometric analysis (IGA) employing first-order shear deformation theory (FSDT) is proposed and implemented for the static and transient analysis of sandwich composite plates. By using Hamilton's principle, the governing equation of motion is derived and then discretized using NURBS-based isogeometric approach. The set of governing equations are solved by the Newmark's time integration scheme. The better performance of the present approach in terms of accuracy and reduced computational cost is ascertained by investigating several numerical examples and comparing the evaluated results with different available results in the literature.
