Experimental investigation and COPRAS-based selection of FFF-printed double-walled polygonal conical structures for crashworthiness applications
This study presents a comprehensive experimental investigation into the crashworthiness performance of thin-walled, double-walled polygonal conical structures fabricated via Fused Filament Fabrication (FFF) using enhanced polylactic acid (PLA+) material. The influence of the cross-sectional geometry (square, hexagonal,...
