Deviator stress (kPa)
Axisymmetric triaxial compression: σ3=cell pressure, q=force/corrected area, σ1=σ3+q, p=(σ1+2σ3)/3.
Mean principal stress (kPa)
Axisymmetric triaxial compression: σ3=cell pressure, q=force/corrected area, σ1=σ3+q, p=(σ1+2σ3)/3.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Axisymmetric triaxial compression: σ3=cell pressure, q=force/corrected area, σ1=σ3+q, p=(σ1+2σ3)/3. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
