چکیده: (211 مشاهده)
A trapezoidal sandwich panel with a mild steel honeycomb core was modeled under high-velocity impact loading generated by high-energy materials. Numerical simulations were performed at three impact energy levels for five sandwich panel configurations and an equivalent square plate of the same mass, for use in certain special vehicles. The deformation response of the sandwich panels and the equivalent square plate was comparatively evaluated. The results showed that the equivalent square plate exhibits the lowest specific energy absorption and the highest peak transmitted load among all the tested configurations. Panel P3, with approximately 145% higher energy absorption and about 190% lower peak transmitted force compared with the equivalent square plate, was identified as the most efficient design for impact energy dissipation. Therefore, this panel can be proposed as a cost-effective and efficient energy absorber for protecting equipment and occupants in various industrial applications.
