*SHEAR FAILURE

Data lines to deﬁne the failure strain in tabular form (TYPE=TABULAR):

First line:

1. Equivalent plastic strain at failure, .

2. Rateof equivalent plastic strain, .

3. Dimensionlesspressure-deviatoric stress ratio, .

4. Temperature.

5. Firstﬁeld variable.

6. Second ﬁeld variable.

7. Etc., up to four ﬁeld variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater thanfour):

1. Fifthﬁeld variable.

2. Etc.,up to eight ﬁeld variables per line.

Repeat this set of data linesas often as necessar y to deﬁne the dependence of strainat failure on plastic

strain, plastic strainrate, stress ratio and, if needed, on temperature and other predeﬁned ﬁeld variables.

Data line to deﬁne the Johnson-Cook shear failure criterion (TYPE=JOHNSONCOOK):

First (and only) line:

1. Johnson-Cook failure parameter, .

2. Johnson-Cook failure parameter, .

3. Johnson-Cook failure parameter, .

4. Johnson-Cook failure parameter, .

5. Johnson-Cook failure parameter, .
