Negative Cohesion "c" CU Triaxial 3 Stage?
Negative Cohesion "c" CU Triaxial 3 Stage?
(OP)
Hello, we run 3-stage CU tests, and had one that created a very steep failure envelope tangent to the Mohr circles that crossed the Y axis below 0. That would give us a cohesion value that is negative. Is that even possible? Would you just call the cohesion 0 and plot the failure envelope through the 0 point? Thanks.

Have you looked at the p-q plots? What do they indicate?
