Hyperfoam(...)

This method creates a Hyperfoam object.

Path

mdb.models[name].materials[name].Hyperfoam
session.odbs[name].materials[name].Hyperfoam

Required arguments

None.

Optional arguments

testData

A Boolean specifying whether test data are supplied. The default value is OFF.

poisson

None or a Float specifying the effective Poisson's ratio, ν, of the material. This argument is valid only when testData=ON. The default value is None.

n

An Int specifying the order of the strain energy potential. Possible values are 1 ≤n≤ 6. The default value is 1.

temperatureDependency

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

moduli

A SymbolicConstant specifying the time-dependence of the material constants. Possible values are INSTANTANEOUS and LONG_TERM. The default value is LONG_TERM.

table

A sequence of sequences of Floats specifying the items described below. This argument is valid only when testData=OFF. The default value is an empty sequence.

Table data

The items in the table data specify the following for values of n:

  • μi and αi for i from 1 to n.

  • νi.

  • Temperature, if the data depend on temperature. Temperature dependence is not allowed for 4 ≤n≤ 6 in an Abaqus/Explicit analysis.

Return value

A Hyperfoam object.

Exceptions

RangeError.

setValues(...)

This method modifies the Hyperfoam object.

Required arguments

None.

Optional arguments

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

Return value

None.

Exceptions

RangeError.
