Description
Manuel Rubio and colleagues find a shortcut for measuring how stiff a soft tube material is, in a 2026 study. Soft tubes show up in pumps, implants, and body passages, and knowing their stiffness guides design. The team paired computer models with bench tests on tubes of two materials, watching how volume swelled as inside pressure beat outside pressure.
For long, thin tubes the patterns lined up neatly. Cutting wall thickness tenfold cut the needed pressure tenfold for the same swell. Tube length stopped mattering once tubes ran long enough. All the curves for such tubes merged into one master curve when plotted the right way. Reading one pressure test against that curve then gives the stiffness, with just a simple pressure gauge.
