MohrCoulombPlasticity(...)

This method creates a MohrCoulombPlasticity object.

Required arguments

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

deviatoricEccentricity

None or a Float 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 Float 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 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.

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.

setValues(...)

This method modifies the MohrCoulombPlasticity object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the MohrCoulombPlasticity method.

Return value

None.

Exceptions

RangeError.

Members

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

In addition, the MohrCoulombPlasticity object can have the following members:

mohrCoulombHardening

A MohrCoulombHardening object.

tensionCutOff

A TensionCutOff object.
