Several approaches such as two-dimensional shear deformation and higher order theories, three-dimensional exact elasticity method and 2-D, 3-D finite element procedures are available in predicting the natural frequencies of composite laminates. In all, a 3-D FEM assists in developing a model for structures with complex constraints, materials and complex geometries. But FE directs an approach that obtains an approximation in solution that depends on discretization type and the polynomials methoddoi:10.13111/2066-8201.2022.14.4.12 fatcat:yl6l2mniofeubholui5ootfsua
