Free Vibration Analysis of Composite Wings Using Differential Quadrature Method with Mechanical Properties

Abstract:

In this study, the natural frequencies of composite wings are investigated using the differential quadrature method (DQM) with Mechanical Properties. DQM is an efficient discretization technique for obtaining accurate numerical solutions to initial and/or boundary value problems using a considerably small number of grid points. In this way, a theoretical DQM model for the laminated composite beam has been developed. Some of the results obtained from DQM are compared with the results obtained in the literature. It has been seen that all of the results considered are very close to each other. It is also been concluded that the bending-torsional coupling rigidity of the composite beam has great and different influence on the first three natural frequencies.
