The table data for this object are:
- Friction angle (given in degrees), ϕ, at high confining pressure in the p–Rmcq plane.
- Dilation angle, ψ, at high confining pressure in the p–Rmwq plane.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.
- Etc.
The corresponding analysis keywords are:

Parameters
----------
table
A sequence of sequences of Floats specifying the items described below.
deviatoricEccentricity
None or a Float specifying the flow potential eccentricity in the deviatoric plane, e;
1/2 ≤ 1.0. If *deviatoricEccentricity*=None, Abaqus calculates the value using the
specified Mohr-Coulomb angle of friction. The default value is None.
meridionalEccentricity
A Float specifying the flow potential eccentricity in the meridional plane, ϵϵ. The
default value is 0.1.
temperatureDependency
A Boolean specifying whether the data depend on temperature. The default value is OFF.
dependencies
An Int specifying the number of field variable dependencies. The default value is 0.
useTensionCutoff
A Boolean specifying whether tension cutoff specification is needed. The default value
is OFF.
Returns
