Low-Velocity Impact Behaviour of Biomimetic Cornstalk-Inspired Lightweight Structures
This study investigates the dynamic response and damage characteristics of cornstalk-inspired lightweight structures. Specimens were fabricated via 3D printing using Acrylonitrile Butadiene Styrene (ABS) as the chosen thermoplastic due to its toughness and resistance to impact. Low-velocity impact tests were conducted at varying incident energies, with subsequent damage analyses performed using X-ray CT scans. The effect of geometrical variations in the constituents on energy-absorbing capability was also investigated. The results demonstrate a ~14% increase in specific energy absorption (SEA) compared to quasi-static measurements. This research is built upon the authors’ previous work on the quasi-static response of the cornstalk-inspired design.
