Abstract:
This paper reports the results of an analytical investigation into the effects of compliant layering on damped beams. The beams consist of laminated face sheets sandwiching a single damping layer. Compliant layering is introduced into this construction by making the extensional modulus of the inner layers of the face sheets substantially less than that of the outer layers. The analytical model, that is used to determine the mechanical response of this type of structure, is based upon a generalization of constrained layer theory. The analysis predicts that compliant layering can be used to reduce the forced response and improve the modal damping.
