Set
DEFINITION=RAMBERG-OSGOOD
to specify the hardening behavior using the Ramberg-Osgood formula.
Set
DEFINITION=TABULAR
to specify the hardening curve in the tabular form.
Optional parameters
DEPENDENCIES
Set this parameter equal to the number of field variable
dependencies included in the definition of hardening behavior, in addition
to temperature. If this parameter is omitted, the hardening behavior does
not depend on field variables.
Data lines for
DEFINITION=RAMBERG-OSGOOD
First line
K. (Units of FL−2.)
n. (Dimensionless.)
Temperature.
First field variable.
Second field variable.
Etc., up to five field variables.
Subsequent lines (only needed if the
DEPENDENCIES parameter has
a value greater than five)
Sixth 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 Ramberg-Osgood model parameters on
temperature and other predefined field variables.
Data lines for
DEFINITION=TABULAR
First line
Yield stress.
Plastic strain.
Temperature.
First field variable.
Second field variable.
Etc., up to five field variables.
Subsequent lines (only needed if the
DEPENDENCIES parameter has
a value greater than five)
Sixth 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 yield stress on plastic strain and, if needed,
on temperature and other predefined field variables.
