The original Cam-Clay (Roscoe & Burland, 1968) yield surface: [ f = q + M p' \ln\left( \fracp'p'_0 \right) = 0 ] where ( p'_0 ) = pre-consolidation pressure (hardening variable). A very specific request

: A mathematical relationship that dictates the direction and magnitude of plastic strain increments once the yield limit is reached. Geomechanics often employs non-associated flow rules
