The Expansion object specifies thermal expansion.
import material mdb.models[name].materials[name].expansion import odbMaterial session.odbs[name].materials[name].expansion
This method creates an Expansion object.
mdb.models[name].materials[name].Expansion session.odbs[name].materials[name].Expansion
Required arguments
Optional arguments
A SymbolicConstant specifying the type of expansion. Possible values are ISOTROPIC, ORTHOTROPIC, ANISOTROPIC, and SHORT_FIBER. The default value is ISOTROPIC.
A Boolean specifying whether a user subroutine is used to define the increments of thermal strain. The default value is OFF.
A Float specifying the value of
if the thermal expansion is temperature-dependent or field-variable-dependent. The default value is 0.0.
A Boolean specifying whether the data depend on temperature. The default value is OFF.
An Int specifying the number of field variable dependencies. The default value is 0.
A sequence of sequences of Floats specifying the items described below. The default value is an empty sequence.
This argument is required only if type is not USER.
Table data
If type=ISOTROPIC, the table data specify the following:
in Abaqus/Standard or Abaqus/Explicit analysis, or 
in Abaqus/CFD analysis.
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.

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.

Required arguments
Optional arguments
The optional arguments to setValues are the same as the arguments to the Expansion method.
Return value
Exceptions
RangeError.
The Expansion object has members with the same names and descriptions as the arguments to the Expansion method.
