*SWELLING

Specify time-dependent volumetric swelling.

This option is used to specify time-dependent metal swelling for a material. Swelling behavior defined by this option is active only during SOILS, CONSOLIDATION; COUPLED TEMPERATURE-DISPLACEMENT; and VISCO procedures.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the volumetric swelling strain rate in addition to temperature. If this parameter is omitted, it is assumed that the volumetric swelling strain rate is constant or depends only on temperature. See Material Data Definition for more information.

LAW

Set LAW=INPUT (default) to define the swelling behavior on the data lines.

Set LAW=USER to define the swelling behavior in user subroutine CREEP.

Data lines for LAW=INPUT

First line

  1. Volumetric swelling strain rate.

  2. Temperature.

  3. First field variable.

  4. Second field variable.

  5. Etc., up to six field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than six)

  1. Seventh field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define the dependence of volumetric swelling strain rate on temperature and other predefined field variables.
