| Abstract | ||
| Designing lightweight structures with high energy absorption capability is a key challenge in engineering applications subjected to impact loading, such as marine, aerospace, and automotive. Sandwich panels with corrugated cores offer a promising solution due to their structural efficiency and customizable geometry. This study investigates the crashworthiness of aluminum corrugated-core sandwich panels under planar impact, focusing on the influence of design parameters such as face sheet thickness, core wall thickness, and core corrugation angle. A parametric approach is adopted to examine how these variables affect the panel’s deformation response and energy absorption behavior while altering one parameter and keeping the other parameters constant. Additionally, a stiffened panel of equivalent weight is modeled for performance benchmarking. The investigation employs numerical simulations to assess structural efficiency through force–displacement response, internal energy accumulation, and specific energy absorption (SEA) criteria. The findings aim to support the development of lightweight panel designs for impact-critical applications. | ||
