How thin tubes fail under external pressure—and what that means for engineering
This concise study traces the history and key findings on the collapse of short, thin tubes. It explains how early formulas gave way to observations from modern experiments, and it shows how tube length, diameter, and wall thickness influence collapsing pressure across brass, steel, glass, and rubber tubes. The material combines historical context with practical curves and conclusions that help readers understand when a tube’s strength will hold or give way.
The work reviews classic results and the evolution of theory, from Fairbairn’s formula to Carman’s experiments, and it summarizes how the collapse pressure varies with length. It highlights the existence of a minimum or “critical” length for many tubes, and it notes that short tubes can behave very differently from long ones. The volume also presents observed pressure–length curves and practical guidance for applying these ideas to different materials and thicknesses.
