This option is used to define a restricted set of mathematical functions to represent yield or limiting surfaces in the space spanned by connector available components. It can be used only in conjunction with the following options: *CONNECTOR DAMAGE EVOLUTION, *CONNECTOR DAMAGE INITIATION, *CONNECTOR FRICTION, or *CONNECTOR PLASTICITY.

This parameter can be used only if OPERATOR=SUM.
Set this parameter equal to the inverse of the overall exponent in the potential definition, . must be a positive number. The default value is .
Set OPERATOR=SUM (default) to define the potential as the sum of the contributions defined on each data line.
Set OPERATOR=MAX to define the potential as the contribution coming from the data line that yields the maximum value. The EXPONENT parameter is ignored in this case.
First line:
Connector component number (1–6) or connector derived component name that is used in the contribution.
Nonzero scaling factor R. The default value is .
Positive exponent . The default value is that of the EXPONENT parameter, . The exponent is ignored if OPERATOR=MAX.
The function H to be used to generate the contribution. H can be ABS (absolute value), MACAULEY (Macauley bracket), or NONE (the identity function). NONE can be used only if . The default value is ABS.
Shift factor a. The default value is .
Sign of this contribution s. The only admissible values are (default) and .
Repeat this data line as often as necessary to define the potential.
