MohrCoulombPlasticity(const odb_SequenceSequenceDouble& table,
                      odb_Union deviatoricEccentricity,
                      double meridionalEccentricity,

                      int dependencies,
                      bool useTensionCutoff);

Required arguments

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

deviatoricEccentricity

The string "NONE" or a Double specifying the flow potential eccentricity in the deviatoric plane, e; 1/2 ≤e≤ 1.0. If deviatoricEccentricity="NONE", Abaqus calculates the value using the specified Mohr-Coulomb angle of friction. The default value is "NONE".

meridionalEccentricity

A Double specifying the flow potential eccentricity in the meridional plane, ϵ. The default value is 0.1.

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is false.

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 false.

Table data

The table data specify the following:

  • Friction angle (given in degrees), ϕ, at high confining pressure in the p–Rm⁢c⁢q plane.

  • Dilation angle, ψ, at high confining pressure in the p–Rm⁢w⁢q 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.

Return value

A MohrCoulombPlasticity object.

Exceptions

RangeError.

Members

The MohrCoulombPlasticity object has members with the same names and descriptions as the arguments to the MohrCoulombPlasticity method.
