Calculation method
Calculation method
Apparent cohesion intercept (kPa)
Mohr-Coulomb least-squares line τ=c+σnormal×tanφ; outputs are apparent fitted parameters.
Apparent friction angle (degrees)
Mohr-Coulomb least-squares line τ=c+σnormal×tanφ; outputs are apparent fitted parameters.
Shear-stress residuals (JSON)
Mohr-Coulomb least-squares line τ=c+σnormal×tanφ; outputs are apparent fitted parameters.
Symbols and units
- a
- Normal effective stresses (kPa)
- b
- Failure shear stresses (kPa)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Mohr-Coulomb least-squares line τ=c+σnormal×tanφ; outputs are apparent fitted parameters. 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.
