*CAST IRON TENSION HARDENING

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

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

This page discusses:

Optional parameters

DEPENDENCIES

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

Data lines to define tension hardening

First line
  1. Yield stress in uniaxial tension, σt.

  2. 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.
