*TENSION CUTOFF

Specify tension cutoff data for the Mohr-Coulomb plasticity model.

This option is used to specify tension cutoff data to limit the load-carrying capacity of the Mohr-Coulomb plasticity model near the tensile region. This option must be used in conjunction with MOHR COULOMB and MOHR COULOMB HARDENING options.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the tension cutoff 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.

Data lines to define tension cutoff

First data line

  1. Yield stress in uniaxial tension, σt.

  2. Corresponding plastic strain. (The first tabular value entered must always be zero.)

  3. Temperature.

  4. First field variable.

  5. Second field variable.

  6. Etc., up to five field variables.

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

  1. Sixth 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 tension cutoff on predefined field variables.
