Correction for rubber membrane in CU triaxial test
Correction for rubber membrane in CU triaxial test
(OP)
Hi,
Everyone can guide to correct for rubber membrane in CU triaxial test. The diameter specimen is 38mm, height to diameter ratio is 2. The thickness rubber membranes is 0.012''. I don't know to choose Young's modulus suitable value.
Thanks,
YP

Dave...I thought you would have figured it out after about #10.

From my graduate lab class:
Membrane resistance (N) = -pi*initial membrane diameter* thickness * 140 N/cm^2 * (axial strain +0.66*volumetric strain)
Volumetric strain is 0 for undrained shear

Your formula is very good. But this is your experiential lab. Where is the formula refer? Book or paper names?
