![]() studied the global bifurcations and multipulse chaotic dynamics of a four-edge simply supported honeycomb sandwich rectangular plate under combined in-plane and transverse excitations. investigated the forced vibration of symmetric rectangular honeycomb sandwich panels with clamped boundaries under transverse excitations, as well as forced vibration of symmetric rectangular honeycomb sandwich panels with simply supported under transverse excitations and lateral water pressure. Cielecka and Jedrysiak applied non-asymptotic continuum model of honeycomb lattice-type plates to the analysis of dynamic problems. extended the Layerwise/Solid-Element method to the static responses and free vibration analysis for the composite sandwich plates with multi-layer cores. dealed with the free vibration analysis of composite sandwich cylindrical shell with a flexible core using a higher order sandwich panel theory. ![]() researched the free flexural vibration of symmetric rectangular honeycomb panels having SCSC edge supports, and improved Reddy’s third-order shear deformation theory. Yu SD studied the free flexural vibration of symmetric rectangular honeycomb panels having simple support boundary conditions. determined the mechanical properties of auxetic tubes with inverted hexagonal honeycombs under pure bending. investigated the buckling response of honeycomb sandwich composite shells with cutouts under axial compression. provided safe lower bounds for the buckling of geometrically imperfect, axially loaded sandwich cylindrical shells with reduced stiffness method. investigated the buckling of a sandwich cylindrical shell under uniform external hydrostatic pressure. Chen and Davalos developed an analytical model that permits the computation of stiffnesses as well as interfacial stresses considering the skin-effect for hexagonal honeycomb sandwich, subjected to in-plane and out-of-plane forces. Lai found that the honeycomb core could be equivalent to an orthotropic layer in bending vibration analysis through experiments and three-dimensional model analysis. used the classical plate theory, first-order and third-order deformation theories to study the buckling and free vibration behavior of cross-ply rectangular composite laminates under various boundary conditions. ![]() Webber discussed the governing elasticity equations for sandwich shells of double curvature. Allen proposed the antiplane hypothesis, the honeycomb core layer has in the antiplane strain state, and the skins obeyed the Kirchhoff hypothesis. Researchers have worked for many years on the vibration of honeycomb sandwich plates and shells. In order to ensure the safety and stability of these structures, it is necessary to consider the nonlinear forced vibration characteristics of these structures in their dynamic design. Honeycomb sandwich shell, as a common honeycomb sandwich material in engineering applications, can be used to make rocket and missile head shell, engine tail nozzle, spacecraft fairing, solar cell shell and so on. ![]() Honeycomb sandwich construction is commonly used in aircraft structures because of its superior specific strength and specific stiffness. The variation of nonlinear strength, multivalued jump point and multivalued region are detailed and discussed. The amplitude-frequency response curves demonstrate softening nonlinearity in primary resonance (no internal resonance), hardening nonlinearity in 3 order superharmonic resonance and no jump phenomenon in 1/3 subharmonic resonance. The influence of structural parameters, the transverse exciting force amplitude and transverse damping to the double curvature honeycomb sandwich shell are discussed by using the analytic approximation method. Based on the homotopy analysis method, the average equations of the primary resonance and harmonic resonance are obtained. The nonlinear governing equations of the double curvature honeycomb sandwich shell subjected to transverse excitations are derived by using Hamilton’s principle and Reddy’s third-order shear deformation theory. Dynamics of a double curvature honeycomb sandwich shell with simply supported boundaries are studied in this paper. ![]()
