Figure F4. A. Comparison between the measured fluid discharge (circles), and the square root of time solution for a semi-infinite length sample (solid line) for Sample 195-1200E-5H-3, 51-61 cm. B. Comparison between the measured fluid discharge (circles) and the finite difference solution (dashed line) for Sample 195-1200E-5H-3, 51-61 cm. The fluid discharge is proportional to axial strain. Note that at longer times the measured discharge and the finite difference solution approach an asymptotic value of discharge, whereas the square root of time discharge will increase without bound.
