In the Plot panel, compare the elastic and plastic
stresses for the test data and the response curve.
The elastic regions of the two curves are fairly similar, so you can exclude
Young's
modulus from the calibration.
However, the curves diverge in the plastic regions, so keep the plastic
parameters in the calibration.
-
From the Material model section of the
Calibration Setup panel, do the following:
-
From the Elastic, Isotropic parameters, clear
the row for the E parameter to exclude it from
the calibration.
-
From the Plastic, Isotropic, Johnson-Cook
parameters, select only the rows for the parameters
A, B, and
n. All three are material parameters that
factor into the algorithm for the Johnson-Cook plasticity model.
