*DENSITY
Specify material mass density.

This option is used to define a material's mass density.

Type: Model data

Optional parameter:

DEPENDENCIES

Set this parameter equal to the number of field variables included in the definition of the density, in addition to temperature. If this parameter is omitted, it is assumed that the density is constant or depends only on temperature. See “Specifying field variable dependence” in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis User's Manual, for more information.

Data lines to define mass density: 

First line:

  1. Mass density. (Units of ML–3.)

  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 density as a function of temperature and other predefined field variables.
