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 aluminum foam-cored (AFP) identical dimensions weight. It has been found AXP far superior to AFP in ballistic resistance because material concentration at impacted area due negative Poisson's ratio (NPR) effect. A parametric study carried out...
The dynamic responses of honeycomb sandwich panels (HSPs) subjected to in-plane projectile impact were studied by means explicit nonlinear finite element simulations using LS-DYNA. HSPs consisted two identical aluminum alloy face-sheets and an core featuring three types unit cell configurations (regular, rectangular-shaped, reentrant hexagons). ballistic resistances with the first analyzed. It was found that HSP auxetic has best resistance, due negative Poisson's ratio effect core....
In the past decades, auxetic metamaterials have attracted extensive interest due to their excellent mechanical properties. this study, we proposed a novel three-dimensional (3D) reentrant circular (REC) metamaterial, and investigated its quasi-static crushing responses through experimental tests numerical simulations. The 3D REC were fabricated by additive manufactured (AM) technique based on different polymer matrix materials, including polyamide-carbon fiber (PA-CF), polyamide (PA)...
Armor steel is widely used for ballistic resistance in military infrastructures and vehicles. However, the high areal density of monolithic plates presents challenges balancing protection maneuverability. This study focuses on a novel armor design, invented by authors: An N-shaped perforated plate (NPAP). The NPAP consists plate, an inclined back plate. A validated finite element (FE) model was to analyze dynamic damage behavior target projectile under impact. Numerical simulation revealed...
Two major requirements for a vehicular system's crash components are being lightweight and having good crashworthiness. Thin-walled round conical tubes, which either empty or foam filled that can potentially be used as the front rails of passenger car subjected to oblique impact, numerically analysed using finite element method. The tube was found have best performance in terms both specific energy absorption peak crushing force. A maximum 106.6% increase observed than foam-filled load angle...
The protection of critical infrastructure, including government buildings, airports, religious military buildings and vehicles, which are at risk to blast loads, has become important due increasing terrorist activities in recent years. Sacrificial cladding systems based on negative Poisson’s ratio core topologies have recently received more attention as a protective technology its excellent energy absorption capability. In this study, field tests were performed metallic re-entrant...
