Modeling Segmented Active Constrained Layer Damping Using Hybrid Dispacement Field

摘要

A finite element model for composite plates with active constrained layer damping is developed using hybrid displacement fields. The higher-order displacement field is used in the composite plate to capture the transverse shear deformations. Because viscoelastic layer and piezoelectric layers are made from certain isotropic materials, the first-and the second-order displacement fields are employed in these layers to maintain computational efficiency in solving the problem.
