bulk-maximum f

maximum elastic bulk modulus, $K_{max}$

kappa f

slope of elastic swelling line, $\kappa$

lambda f

slope of normal consolidation line, $\lambda$

poisson f

Poisson’s ratio, $\nu$

pressure-reference f

reference pressure, $p_1$

pressure-effective f

mean effective stress, $p$, required since this is a pressure-dependent model.

pressure-preconsolidation f

pre-consolidation pressure, $p_{c0}$

ratio-critical-state f

stress ratio at the critical state, $M = q/p$ at the critical state

shear f

elastic shear modulus, $G$

specific-volume-reference f

specific volume at reference pressure $p_1$ on normal consolidation line, $v_{\lambda}$

bulk f

current elastic bulk modulus, $K$

specific-volume f

[read only] current specific volume, $v$ , initialized or updated internally.

strain-volumetric-total f

[read only] accumulated total volumetric strain.

stress-deviatoric f

[read only] current deviatoric stress, $q$  

Notes:

• If the current bulk modulus, $K$, is greater than $K_{max}$, an error message will suggest increasing $K_{max}$.
• Only one between the Poisson’s ration, $\nu$, and the shear modulus, $G$, is required for input. If $\nu$ is not specified, and a non-zero $G$ is specified, then $G$ remains constant and $\nu$ will change as $K$ changes. If a non-zero $\nu$ is given, then $G$ will change as $K$ changes and $\nu$ remains constant.
