DruckerPragerCreep(...)

This method creates a DruckerPragerCreep object.

Path

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

Prototype

odb_DruckerPragerCreep&
DruckerPragerCreep(const odb_SequenceSequenceDouble& table,
                   const odb_String& law,
                   bool temperatureDependency,
                   int dependencies);

Required arguments

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

law

An odb_String specifying the type of data defining the creep law. Possible values are:

  • "STRAIN", specifying a strain-hardening power law.

  • "TIME", specifying a time-hardening power law.

  • "SINGHM", specifying a Singh-Mitchell type law.

  • "USER", specifying the creep law is input from user subroutine CREEP.

The default value is "STRAIN".

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 law=TIME or law=STRAIN, the table data specify the following:

  • A. (Units of F​-nL​2⁢nT​-1-m.)

  • n.

  • m.

  • 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 law=SINGHM, the table data specify the following:

  • A. (Units of T−1.)

  • α. (Units of F−1L2.)

  • m.

  • t1. (Units of T.)

  • 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 DruckerPragerCreep object.

Exceptions

RangeError.

Members

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