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 are constant or depend only on temperature. See Material Data Definition for more information.

TYPE

Set TYPE=STRAIN (default) to specify the tensile failure based on a tensile cracking strain criterion.

Set TYPE=DISPLACEMENT to specify the tensile failure based on a tensile cracking displacement criterion.

Data lines if the tensile failure is defined based on a tensile cracking strain criterion (TYPE=STRAIN)

First line

Tensile cracking strain at failure, ${({\tilde{ε}}_{t}^{c k})}_{f}$ .
Compressive inelastic (crushing) strain at failure, ${({\tilde{ε}}_{c}^{i n})}_{f}$ .
Tensile damage variable at failure, ${(d_{t})}_{f}$ , if the CONCRETE TENSION DAMAGE option is specified for the material.
Compressive damage variable at failure, ${(d_{c})}_{f}$ , if the CONCRETE COMPRESSION DAMAGE option is specified for the material.
Temperature.
First field variable.
Second field variable.
Etc., up to three field variables.

A material failure criterion is considered only if the corresponding data line entry is positive.

Second line (only needed if the DEPENDENCIES parameter has a value greater than three)

Fourth field variable.
Etc., up to eight field variables per line.

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