*CAST IRON COMPRESSION HARDENING

Specify hardening in compression for the gray cast iron plasticity model.

This option is used to specify the compression hardening data for gray cast iron. It must be used in conjunction with the CAST IRON PLASTICITY and CAST IRON TENSION HARDENING options.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the compressive yield stress, in addition to temperature. If this parameter is omitted, it is assumed that the compressive yield stress depends only on plastic strain and, possibly, on temperature. See Material data definition for more information.

Data lines to define compression hardening

First line

  1. Yield stress in compression, σc.

  2. Absolute value of the corresponding plastic strain. (The first tabular value entered must always be zero.)

  3. Not used.

  4. Temperature.

  5. First field variable.

  6. Etc., up to four field variables.

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

  1. Fifth 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 the yield stress on plastic strain and, if needed, on temperature and other predefined field variables.
