Abstract:

This report describes the formulation of a structural theory for the analysis of laminated anisotropic damped plates. The plates consist of laminated face sheets sandwiching a single damping layer. The displacement degrees of freedom used to construct the analytical model are a generalization of those found in constrained layer theory. Variational principles are used to form the equations of motion which are solved for the steady state response of simply supported semi-infinite plates. The analysis is used to examine the effect of stress coupling and compliant layering on improving the dynamic resistance of damped structures loaded in flexure.
