29.98.1 TensionStiffening(...)

This method creates a TensionStiffening object.

Path

mdb.models[name].materials[name].concrete.TensionStiffening
session.odbs[name].materials[name].concrete.TensionStiffening

Required argument

table

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

Optional arguments

type

A SymbolicConstant specifying how the postcracking behavior is defined. Possible values are DISPLACEMENT and STRAIN. The default value is STRAIN.

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.

Table data

If type=STRAIN, the table data specify the following:

Fraction of remaining stress to stress at cracking.
Absolute value of the direct strain minus the direct strain at cracking.
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:

Displacement, , at which a linear loss of strength after cracking gives zero stress.
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 TensionStiffening object.

Exceptions

RangeError.

29.98.2 setValues(...)

Optional arguments

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

Return value

None

Exceptions

RangeError.
