Specify tension cutoff
data for the Mohr-Coulomb plasticity model.
This option is used to specify tension cutoff data to limit the
load-carrying capacity of the Mohr-Coulomb plasticity model near the tensile
region. This option must be used in conjunction with
MOHR COULOMB and
MOHR COULOMB HARDENING options.
Set this parameter equal to the number of field variable dependencies
included in the definition of the tension cutoff stress, in addition to
temperature. If this parameter is omitted, it is assumed that the tensile yield
stress depends only on the plastic strain and, possibly, on temperature.
Data lines to
define tension cutoff
First
data line
Yield stress in uniaxial tension, .
Corresponding plastic strain. (The first tabular value entered must always
be zero.)
Temperature.
First field variable.
Second field variable.
Etc., up to five field variables.
Subsequent data 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 tension cutoff on
predefined field
variables.
