SHEAR FAILURE

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

First line:

1. Equivalent plastic strain at failure, .

2. Rate of equivalent plastic strain, .

3. Dimensionless pressure-deviatoric stress ratio,

4. Temperature.

5. First ﬁeld variable.

6. Second ﬁeld variable.

7. Etc., up to four ﬁeld variables.

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

1. Fifth ﬁeld variable.

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

Repeat this set of data lines as often as necessary to deﬁne the dependence of strain at failure on plastic

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

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

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,
