29.43.1 DruckerPragerCreep(...)

This method creates a DruckerPragerCreep object.

Path
mdb.models[name].materials[name].druckerPrager.DruckerPragerCreep
session.odbs[name].materials[name].druckerPrager.DruckerPragerCreep

Required argument

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

law

A SymbolicConstant 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 OFF.

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:

  • . (Units of FLT .)

  • .

  • .

  • 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:

  • . (Units of T–1 .)

  • . (Units of F–1L2 .)

  • .

  • . (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.


29.43.2 setValues(...)

This method modifies the DruckerPragerCreep object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the DruckerPragerCreep method.

Return value

None

Exceptions

RangeError.


29.43.3  Members

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