Abstract: This paper deals with the dynamic analysis of pre-stressed laminated
composite plates. Particular emphasis is devoted to the case of in-plane
mono-axial, biaxial, shear and combined loadings. Both equivalent single layer
and layer-wise plate kinematic description are addressed, according to the
hierarchical approach proposed by the Carrera's unified formulation. The
different kinematic approaches are compared in order to identify the
appropriate modeling for laminated composite plates subjected to combined
loadings. The principle of virtual displacement is applied in order to obtain
governing equations and the corresponding problem is solved through the finite
element method. When possible, assessments/comparisons with exact solutions are
proposed. Moreover, the effects of different stacking sequences, boundary
conditions, geometries and materials on plate natural frequencies are
illustrated.
