29.6.1 BrittleFailure(...)

This method creates a BrittleFailure object.

Path

mdb.models[name].materials[name].brittleCracking.BrittleFailure
session.odbs[name].materials[name].brittleCracking.BrittleFailure

Required argument

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

failureCriteria

A SymbolicConstant specifying the failure criteria. Possible values are UNIDIRECTIONAL, BIDIRECTIONAL, and TRIDIRECTIONAL. The default value is UNIDIRECTIONAL.

Table data

If parent BrittleCracking member type=STRAIN the table data specify the following:

Direct cracking failure strain.
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

If parent BrittleCracking member type=DISPLACEMENT or type=GFI the table data specify the following:

Direct cracking failure displacement.
Temperature, if the data depend on temperature.
Value of the first field variable, if the data depend on field variables.
Value of the second field variable.
Etc.

Return value

A BrittleFailure object.

Exceptions

RangeError.

29.6.2 setValues(...)

This method modifies the BrittleFailure object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the BrittleFailure method.

Return value

None

Exceptions

RangeError.

29.6.3 Members

The BrittleFailure object has members with the same names and descriptions as the arguments to the BrittleFailure method.
