A 9-noded Lagrangian plate bending finite element that incorporates first-order transverse shear deformation and rotary inertia is used to predict the free and forced vibration response of sandwich folded plate structures. A 6 x 6 transformation matrix is applied to transform the system element matrices before assembly. An additional drilling degree of freedom is appended with the usual five degrees-of-freedom per node to use the transformation. The finite element results presented here show good agreement with the available semi-analytical solutions and finite element results. Parametric studies are presented for free and forced vibration response for sandwich folded plates, with reference to crank angle and different boundary conditions.
