CrushableFoam object

CrushableFoam(...)

This method creates a CrushableFoam object.

Path

materialApi.materials()[name].CrushableFoam

Prototype

odb_CrushableFoam&
CrushableFoam(const odb_SequenceSequenceDouble& table,
              const odb_String& hardening,
              bool temperatureDependency,
              int dependencies);

Required arguments

table: An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

hardening: An odb_String specifying the type of hardening/softening definition. Possible values are "VOLUMETRIC" and "ISOTROPIC". The default value is "VOLUMETRIC".
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.

Table data

If hardening=VOLUMETRIC, the table data specify the following:

Ratio, $k$ , of initial yield stress in uniaxial compression, $σ_{c}^{0}$ , to initial yield stress in hydrostatic compression, $p_{c}^{0}$ ; 0.0 $< k <$ 3.0.
Ratio, $k_{t}$ , of yield stress in hydrostatic tension, $p_{t}$ , to initial yield stress in hydrostatic compression, $p_{c}^{0}$ . The default value is 1.0.
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.

If hardening=ISOTROPIC, the table data specify the following:

Ratio, $k$ , of initial yield stress in uniaxial compression, $σ_{c}^{0}$ , to initial yield stress in hydrostatic compression, $p_{c}^{0}$ ; 0.0 $\leq k \leq$ 3.0.
Plastic Poisson's ratio. $ν_{p}$ ; -1 $\leq ν_{p} \leq$ 0.5.
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 CrushableFoam object.

Exceptions

RangeError.

Members

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

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