29.7.1 BrittleShear(...)

This method creates a BrittleShear object.

Path

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

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.

type

A SymbolicConstant specifying the type of postcracking shear behavior. Possible values are RETENTION_FACTOR and POWER_LAW. The default value is RETENTION_FACTOR.

Table data

If type=RETENTION_FACTOR the table data specify the following:

Shear retention factor.
Crack opening 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=POWER_LAW the table data specify the following:

e.
p.
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 BrittleShear object.

Exceptions

RangeError.

29.7.2 setValues(...)

Optional arguments

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

Return value

None

Exceptions

RangeError.

29.7.3 Members

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