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.

Read only properties cannot be set by the user. However, they may be listed, plotted, or accessed through FISH.
