MeanFieldVoid(...)

This method creates a MeanFieldVoid object.

Path

mdb.models[name].materials[name].meanFieldHomogenization.MeanFieldVoid
session.odbs[name].materials[name].meanFieldHomogenization.MeanFieldVoid

Required arguments

name
A String specifying the constituent repository key.
table

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

Optional arguments

material

A String specifying the name of the material.

isotropizationCoefficient

A Float specifying the factor used for scaling the plastic strain of the constituent when calculating the isotropic part of the tangent.

volumeFractionType

A SymbolicConstant specifying the type of volume fraction. Possible values are UNIFORM, ANALYTICAL_FIELD, and DISCRETE_FIELD. The default value is UNIFORM.

volumeFractionFieldName

A String specifying the name of the AnalyticalField object or DiscreteField object.

aspectRatioType

A SymbolicConstant specifying the type of aspect ratio. Possible values are UNIFORM, ANALYTICAL_FIELD, and DISCRETE_FIELD. The default value is UNIFORM.

aspectRatioFieldName

A String specifying the name of the AnalyticalField object or DiscreteField object.

orientationTensorType

A SymbolicConstant specifying the type of orientation tensor. Possible values are UNIFORM, ANALYTICAL_FIELD, and DISCRETE_FIELD. The default value is UNIFORM.

orientationTensorFieldName

A String specifying the name of the AnalyticalField object or DiscreteField object.

shape

A SymbolicConstant specifying the type of inclusion shapes. Possible values are SPHERE, PROLATE, OBLATE, CYLINDER, PENNY, and ELLIPTIC_CYLINDER. The default value is SPHERE.

direction

A SymbolicConstant specifying the type of inclusion direction. Possible values are FIXED, RANDOM3D, and ORIENTATION_TENSOR.

strainConcentrationTensor

A sequence of Floats defining the 36 components of the strain concentration tensor.

temperatureGradientConcentrationTensor

A sequence of Floats defining the 9 components of the temperature gradient concentration tensor.

Table data

The table data specify the following:

  • Volume fraction.

  • Aspect ratio.

  • Components of the direction vector defined in the local coordinate system when direction=FIXED. Components of the second-order orientation tensor in the local coordinate system when direction=ORIENTATION_TENSOR.

  • Etc.

Return value

A MeanFieldVoid object.

Exceptions

RangeError.

setValues(...)

This method modifies the MeanFieldVoid object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the MeanFieldVoid(...) method.

Return value

None.

Exceptions

RangeError.

Members

The MeanFieldVoid object has members with the same names and descriptions as the arguments to the MeanFieldVoid(...) method.
