Abstract
A finite element is presented for the dynamic analysis of laminated beams. A discrete layer approach is used to specify the in-plane displacement field through the thickness. The element enforces C0 continuity of in-plane displacements and C1 continuity of the transverse displacement at end nodes, making it immune to the effects of shear locking. A consistent form of the mass matrix is used and both transverse and rotatory inertia are included. The element is used to predict natural frequency and damping in composite sandwich beams augmented with a viscoelastic damping layer. Damping is calculated by both the Modal Strain Energy and Complex Modulus methods. The finite element predictions are compared to experimental data for composite sandwich beams.
