Plastic(const odb_SequenceSequenceDouble& table,
        const odb_String& hardening,
        bool rate,

        bool strainRangeDependency,
        int numBackstresses,
        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. Possible values are "ISOTROPIC", "KINEMATIC", "COMBINED", "JOHNSON_COOK", and "USER". The default value is "ISOTROPIC".
rate: A Boolean specifying whether the data depend on rate. The default value is false.
dataType: An odb_String specifying the type of combined hardening. This argument is only valid if hardening="COMBINED". Possible values are "HALF_CYCLE", "PARAMETERS", and "STABILIZED". The default value is "HALF_CYCLE".
strainRangeDependency: A Boolean specifying whether the data depend on strain range. This argument is only valid if hardening="COMBINED" and dataType="STABILIZED". The default value is false.
numBackstresses: An Int specifying the number of backstresses. This argument is only valid if hardening="COMBINED". The default value is 1.
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=ISOTROPIC, or if hardening=COMBINED and dataType=HALF_CYCLE, the table data specify the following:

Yield stress.
Plastic strain.
Equivalent plastic strain rate, ${\dot{\bar{ε}}}^{p l}$ .
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=COMBINED and dataType=STABILIZED, the table data specify the following:

Yield stress.
Plastic strain.
Strain range, if the data depend on strain range.
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=COMBINED and dataType=PARAMETERS, the table data specify the following:

Yield stress at zero plastic strain.
The first kinematic hardening parameter, $C_{1}$ .
The first kinematic hardening parameter, $γ_{1}$ .
If applicable, the second kinematic hardening parameter, $C_{2}$ .
If applicable, the second kinematic hardening parameter, $γ_{2}$ .
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.

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

Yield stress.
Plastic strain.
Temperature, if the data depend on temperature.

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

A.
B.
n.
m.
Melting temperature.
Transition temperature.

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

Hardening properties.

Return value

A Plastic object.

Exceptions

RangeError.
