[advanced] name of the table relating to $m_b$ to $e^p_3$.

table-multiplier s

[advanced] name of the table relating a multiplier to $\sigma_3$.

table-s s

[advanced] name of the table relating $s$ to $e^p_3$.

table-sci s

[advanced] name of the table relating $\sigma_{ci}$ to $e^p_3$.

strain-3-plastic f

[read only] accumulated plastic strain in direction of least compressive principal stress, $e^p_3$

Notes:

• Only one of the two options is required to define the elasticity: bulk modulus $K$ and shear modulus $G$, or Young’s modulus $E$ and Poisson’s ratio $\nu$. When choosing the latter, Young’s modulus $E$ must be assigned in advance of Poisson’s ratio $\nu$.

Footnotes

Advanced properties have default values and do not require specification for simpler applications of the model.

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