Prototype

odb_RateDependent&
RateDependent(const odb_SequenceSequenceDouble& table,
              const odb_String& type,
              bool temperatureDependency,
              int dependencies);

Required arguments

table: An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

type: An odb_String specifying the type of rate-dependent data. Possible values are "POWER_LAW", "YIELD_RATIO", and "JOHNSON_COOK". The default value is "POWER_LAW".
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 type=POWER_LAW, the table data specify the following:

$D$ .
$n$ .
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 type=YIELD_RATIO, the table data specify the following:

Yield stress ratio, $R = \bar{σ} / σ^{0}$ .
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 type=JOHNSON_COOK, the table data specify the following:

$C$ .
${\dot{ε}}_{0}$ .

Return value

A RateDependent object.

Exceptions

RangeError.

Members

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