Anti-penetration performance and design of composite hangar door under long rods impact
To address the threat of long rods projectile (LRP) to hangar doors, this study designed a metal-UHMWPE composite armor door, comprising G50 steel front and rear face sheets, a Q345 steel honeycomb core, and filled UHMWPE laminates. A finite element (FE) model was established using the LS-DYNA software to verify the pr...
