59.44.1 DruckerPragerHardening(...)

This method creates a DruckerPragerHardening object.

Path

materialApi.materials()[name].druckerPrager().DruckerPragerHardening

Prototype

odb_DruckerPragerHardening&
DruckerPragerHardening(const odb_SequenceSequenceDouble& table,
                       const odb_String& type,
                       bool rate,
                       bool temperatureDependency,
                       int dependencies);

Required argument

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

type

An odb_String specifying the type of data defining the hardening behavior. Possible values are "COMPRESSION", "TENSION", and "SHEAR". The default value is "COMPRESSION".

rate

A Boolean specifying whether the data depend on rate. The default value is false.

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

Yield stress.
Absolute value of the corresponding plastic strain. (The first tabular value entered must always be zero.)
Equivalent plastic strain rate, , for which this hardening curve applies.
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 DruckerPragerHardening object.

Exceptions

RangeError.
