This research aims to understand the effects of geometric parameters on the impact performance of multilayer honeycomb sandwich structures.
Combined experimental and numerical approaches to assess low-velocity impact behavior.
Analysis of different impact energy levels.
Examination of geometric parameters like face sheet thickness, core wall thickness, and core height.
Impact responses identified as multipeak, single-peak, and plateau-type modes.
Multipeak mode involves perforation, while single-peak mode shows deformation among face sheets.
Higher face sheet thickness increases impact resistance, and reduced core height enhances efficiency at low energies.
