Implication

Comparative analysis reveals polyurethane foam enhances energy absorption in polyethylene tubes, suggesting design improvements for load-bearing applications.

Key Points

Foam-filled polyethylene tubes demonstrated superior energy absorption compared to empty tubes, enhancing structural efficiency.
Increasing tube length and wall thickness contributed positively to load-bearing capacity, as showed by higher energy absorption metrics.
Diameter affects energy absorption differently; smaller diameters improve it in empty tubes, while larger diameters do so in foam-filled tubes.
Identified damage mechanisms included foam fracture and densification, highlighting foam's critical role in tube performance.
