“…To understand the impact response and damage behaviors of sandwich structures, many researchers have studied the behavior of structures under low velocity impact loading (Mines et al, 1998;Dear et al, 2005;Kim and Jun, 1992;Kenny and Torre, 1999). Mines et al (1998) have described the low velocity perforation performance for a series of materials and geometry combinations and identified that their failure mechanism and energy absorption capability are governed by core and impact velocity.…”

“…For example, Research of J.P.Dear et al [10] was about the impact toughness of honeycomb sandwich panels prepared from sheet molding compound (SMC), glass mat thermoplastic (GMT) and different skin and core materials. It was shown that SMC sandwich panels have the highest impact energy absorbed, since GF content of SMC is up to 62%.…”

Abstract.As the light-weight and high-strength thermoplastic composites, novel honeycomb sandwich panels were discussed in this paper: continuous glass fiber reinforced polypropylene (GF/PP) laminated sheets were used as the surface and polypropylene (PP) honeycomb was used as the core. The effects of honeycomb core's height, thickness and aperture on the mechanical properties were analyzed in this paper. The composite honeycomb sandwich panels exhibited excellent bending strength at 37.6MPa and lateral pressure strength at 25.8MPa.

“…Ruzzene [7] analyzed the vibration and the sound radiation from hexagonal and re-entrant sandwich beams with truss core. Dear et al [8] studied the impact toughness of different lightweight sandwich panels and composite sheet materials by experiments. Chen and Davalos [9] developed an analytical model that permits the computation of stiffness as well as interfacial stresses and considered the skin-effect for hexagonal honeycomb sandwich subjected to in-plane and out-of-plane forces.…”

The global bifurcations and multi-pulse chaotic dynamics of a simply supported honeycomb sandwich rectangular plate under combined parametric and transverse excitations are investigated in this paper for the first time. The extended Melnikov method is generalized to investigate the multi-pulse chaotic dynamics of the non-autonomous nonlinear dynamical system. The main theoretical results and the formulas are obtained for the extended Melnikov method of the non-autonomous nonlinear dynamical system. The nonlinear governing equation of the honeycomb sandwich rectangular plate is derived by using the Hamilton's principle and the Galerkin's approach. A two-degree-of-freedom non-autonomous nonlinear equation of motion is obtained. It is known that the less simplification processes on the system will result in a better understanding of the behaviors of the multi-pulse chaotic dynamics for high-dimensional nonlinear systems. Therefore, the extended Melnikov method of the non-autonomous nonlinear dynamical system is directly utilized to analyze the global bifurcations and multi-pulse chaotic dynamics of the two-degree-of-freedom non-autonomous nonlinear system for the honeycomb sandwich rectangular plate. The theoretical results obtained here indicate that multi-pulse chaotic motions can occur in the honeycomb sandwich rectangular plate. Numerical simulation is also employed to find the multi-pulse chaotic motions of the honeycomb sandwich rectangular plate. It also demonstrates the validation of the theoretical prediction.
