59.5 BrittleCracking object

The BrittleCracking object specifies cracking and postcracking properties for the brittle cracking material model.

Access

materialApi.materials()[name].brittleCracking()

59.5.1 BrittleCracking(...)

This method creates an BrittleCracking object.

Path

materialApi.materials()[name].BrittleCracking

Prototype

odb_BrittleCracking&
BrittleCracking(const odb_SequenceSequenceDouble& table,
                bool temperatureDependency,
                int dependencies,
                const odb_String& type);

Required argument

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

temperatureDependency

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

dependencies

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

type

An odb_String specifying the type of postcracking behavior. Possible values are "STRAIN", "DISPLACEMENT", and "GFI". The default value is "STRAIN".

Table data

If type=STRAIN the table data specify the following:

Remaining direct stress after cracking.
Direct cracking 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 type=DISPLACEMENT the table data specify the following:

Remaining direct stress after cracking.
Direct cracking 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.

If type=GFI the table data specify the following:

Failure stress.
Mode I fracture energy.
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 BrittleCracking object.

Exceptions

None.
