This option is used to define the compression hardening data for the concrete damaged plasticity material model. It must be used in conjunction with the *CONCRETE DAMAGED PLASTICITY and *CONCRETE TENSION STIFFENING options. In addition, the *CONCRETE TENSION DAMAGE and/or *CONCRETE COMPRESSION DAMAGE options can be used to specify tensile and/or compressive stiffness degradation damage.

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, the compressive yield stress depends only on the inelastic strain, the strain rate, and, possibly, on temperature. See “Specifying field variable dependence” in “Material data definition,” Section 21.1.2 of the Abaqus Analysis User's Guide, for more information.
First line:
Inelastic (crushing) strain, .
Temperature.
First field variable.
Second field variable.
Etc., up to four field variables.
The first point at each value of temperature must have a crushing strain of 0.0 and gives the initial yield stress value, .
Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four):
Fifth field variable.
Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the dependence of the compressive yield stress on crushing strain, crushing strain rate, and other predefined field variables.
