TensionStiffening object

The TensionStiffening object defines the retained tensile stress normal to a crack in a Concrete model.

The following topics are discussed:

Access

materialApi.materials()[name].concrete().tensionStiffening()

TensionStiffening(...)

This method creates a TensionStiffening object.

Path

materialApi.materials()[name].concrete().TensionStiffening

Prototype

odb_TensionStiffening&
TensionStiffening(const odb_SequenceSequenceDouble& table,
                  const odb_String& type,
                  bool temperatureDependency,
                  int dependencies);

Required arguments

table

An odb_SequenceSequenceDouble specifying the items described below.

Optional arguments

type

An odb_String 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 false.

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, u0, 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.

Members

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