Abstract
The dynamic behavior of sandwich panels with a flexible core and debonded region with and without contact is studied. The investigation uses the high-order theory of sandwich panels and considers geometrical nonlinear effects and the nonlinearity associated with the contact characteristics of the delaminated surfaces. The rotary inertia of the face-sheets and the core and the high order velocity and acceleration fields through the depth of the core are included. The dynamic governing equations, boundary conditions and continuity requirements are derived through the Hamilton principle. Numerical results that reveal the influence of the contact characteristics on the dynamic response of the sandwich panel are also presented and discussed.
