*FAIL STRAIN

Define parameters for strain-based failure measures.

This option is used to define the strain limits for strain-based failure measures. It can be used only in conjunction with the ELASTIC option.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the failure criteria, in addition to temperature. If this parameter is omitted, it is assumed that the failure criteria depend only on temperature. See Material data definition for more information.

Data lines to define strain-based failure criteria

First line
  1. Tensile strain limit in fiber direction, Xεt.

  2. Compressive strain limit in fiber direction, Xεc.

  3. Tensile strain limit in transverse direction, Yεt.

  4. Compressive strain limit in transverse direction, Yεc.

  5. Shear strain limit in the XY plane, Sε.

  6. Temperature.

  7. First field variable.

  8. Second field variable.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than two.)
  1. Third field variable.

  2. Fourth field variable.

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

Repeat this set of data lines as often as necessary to define the failure criteria as a function of temperature and other predefined field variables.
