“…The effects of several parameters on the energy dissipation of sandwich panel during axial perforation were experimentally tested by Goldsmith and Sackman [3], including the impact velocity, the boundary condition, and the bonding strength between the honeycomb core and the aluminum faces. Meanwhile, analytical and numerical solutions have been obtained for the ballistic limits of honeycomb sandwich panels subjected to normal projectile impacts [4,5]. It was observed that folding of the cell walls and shearing of the plug play the major role in energy dissipation and ballistic resistance of the aluminum honeycomb panels against projectiles [6].…”

An innovative auxetic-cored sandwich panel (AXP) is proposed. Its perforation resistant performance under high-velocity projectile impact was numerically analyzed using the validated finite element simulation techniques and compared with that of the aluminum foam-cored sandwich panel (AFP) of identical dimensions and weight. It has been found that the AXP is far superior to the AFP in ballistic resistance because of the material concentration at the impacted area due to the negative Poisson's ratio (NPR) effect. A parametric study was carried out to investigate the effects of several key parameters, including impact velocity, face and core thicknesses, and core density, on the ballistic resistance of the AXP and AFP. The results show that the ballistic limit and perforation energy of the AXP is greatly affected by these parameters. Meanwhile, the advantages of AXP over AFP being used as ballistic resistant structures are highlighted. The primary outcome of this research is new information on the development and design of advanced ballistic resistant structures containing auxetic materials.

Development of an Equivalent Composite Honeycomb Model: A Finite Element Study

Finite element analysis of complex geometries such as honeycomb composites, brings forth several difficulties. These problems are expressed primarily as high calculation times but also memory issues when solving these models. In order to bypass these issues, the main goal of this research paper is to define an appropriate equivalent model in order to minimize the complexity of the finite element model and thus minimize computation times. A finite element study is conducted on the design and analysis of equivalent layered models, substituting the honeycomb core in sandwich structures. A comparison is made between available equivalent models. An equivalent model with the right set of material property values is defined and benchmarked, consisting of one continuous layer with orthotropic elastic properties based on different available approximate formulas. This way the complex geometry does not need to be created while the model yields sufficiently accurate results.

“…Studies regarding the collapse mechanism of honeycomb sandwich panels under bending and compression revealed that buckling, debonding and crushing are normally observed (Yeh and Wu 1991;Zhou et al 2006;Hong et al 2006). Furthermore, experimental, analytical and numerical studies on damage and failure behaviour of honeycomb sandwiches were also carried out (Gdoutos et al 2003;Abbadi et al 2009;Crupi et al 2012;Besant et al 2001). Numerical investigations on the failure initiation and propagation of honeycomb sandwich panels under distinct loading conditions, comprising compression (Jeyakrishnan et al 2013), flexural (Wahl et al 2014) and low-velocity impact (Foo et al 2008) were evaluated.…”

Polyester pins are incorporated in polyurethane foam filled honeycomb core sandwich panel to increase the interfacial strength between the faces and core in order to improve the performance of sandwich structures. Foam filled Honeycomb Sandwich panel (FHS) and Pin incorporated Foam filled Honeycomb sandwich panels (PFHS) were developed. The developed sandwich panels are tested for flexural and vibration characteristics. The influence of strain rates on flexural behaviour of sandwich panels were also evaluated. The material used for face sheets and pins are same, ends of pin act as chemically cross linked polyester joint at the interfaces of faces and core in addition to the adhesive area. This modification had effectually increased the interfacial strength thereby increased the flexural and damping properties of panels significantly. Moreover, increasing the pin diameter has a larger effect, whereas, the strain rate had a moderate influence on the failure load of both types of sandwich panels. The investigation brings to light a novel pin incorporated foam filled honeycomb sandwich panels that can be used for various applications.
