This analysis reveals how infill pattern and infill ratio affect crashworthiness in 3D-printed tubes, suggesting optimal configurations for energy absorption.
Key Points
Energy absorption improves with increased infill ratio, but benefits diminish beyond 30%.
Peak crushing force and energy absorption metrics indicate grid and honeycomb infills perform best at 20-30% ratios.
Quasi-static compression tests using PLA printed structures evaluated crashworthiness performance.
The Archimedean chords infill performed poorly due to a greater likelihood of fracturing.
