"""The ConnectorElasticity object defines elastic behavior for one or more components of a
connector's relative motion.
The ConnectorElasticity object is derived from the ConnectorBehaviorOption object.
Attributes
----------
options: ConnectorOptions
A :py:class:`~abaqus.Connector.ConnectorOptions.ConnectorOptions` object specifying the :py:class:`~abaqus.Connector.ConnectorOptions.ConnectorOptions` used to define tabular options
for this ConnectorBehaviorOption.
Notes
-----
This object can be accessed by:
.. code-block:: python
import section
mdb.models[name].sections[name].behaviorOptions[i]
import odbSection
session.odbs[name].sections[name].behaviorOptions[i]
The table data for this object are:
- If *behavior*=LINEAR and *coupling*=UNCOUPLED, then each sequence of the table data specifies the following:
- Elastic stiffness (per each specified force/moment component).
- Frequency (cycles/time), if the data depend on frequency.
- 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 *behavior*=NONLINEAR and *coupling*=UNCOUPLED, then each sequence of the table data specifies the following:
- Force or moment.
- Relative displacement or rotation.
- 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 *behavior*=LINEAR and *coupling*=COUPLED, the table data specify the symmetric portion of the elastic stiffness matrix for the specified components followed by any temperature data and then any field data. For example, if components 2, 3, and 5 are specified, the table portion of the command is as follows:
table=( (D22D22, D23D23, D25D25, D33D33, D35D35, D55D55,),
)
The following items should then be specified as comma-separated data:
- 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 *behavior*=NONLINEAR and *coupling*=COUPLED_POSITION or COUPLED_MOTION, each sequence of the table data specifies the following:
- Force or moment for the directions in the *components* list.
- Relative position or angle for the first *independentComponents* direction if *coupling*=COUPLED_POSITION. Relative displacement or rotation for the first *independentComponents* direction if *coupling*=COUPLED_MOTION.
- Relative position or angle for the second *independentComponents* direction if *coupling*=COUPLED_POSITION. Relative displacement or rotation for the second *independentComponents* direction if *coupling*=COUPLED_MOTION.
- Etc. up to the Nth *independentComponents* direction.
- 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.

Parameters
----------
behavior
A SymbolicConstant specifying whether the elastic behavior is linear, nonlinear, or
rigid. Possible values are LINEAR, NONLINEAR, and RIGID. The default value is LINEAR.
coupling
A SymbolicConstant specifying whether the elastic behavior is coupled between the
connector's components of relative motion. If *behavior*=LINEAR, then possible values
are UNCOUPLED and COUPLED. If *behavior*=NONLINEAR, then possible values are UNCOUPLED,
COUPLED_POSITION, and COUPLED_MOTION. Possible values are UNCOUPLED, COUPLED,
COUPLED_POSITION, and COUPLED_MOTION. The default value is UNCOUPLED.This argument is
not applicable if *behavior*=RIGID.
dependencies
An Int specifying the number of field variable dependencies. The default value is 0.This
argument is not applicable if *behavior*=RIGID.
temperatureDependency
A Boolean specifying whether the behavior data depend on temperature. The default value
is OFF.This argument is not applicable if *behavior*=RIGID.
frequencyDependency
A Boolean specifying whether the behavior data depend on frequency. This value is
applicable only if *behavior*=LINEAR and *coupling*=UNCOUPLED. The default value is
OFF.This argument is not applicable if *behavior*=RIGID.
table
A sequence of sequences of Floats specifying elasticity properties. Items in the table
data are described below. This argument is not applicable if *behavior*=RIGID. The
default value is an empty sequence.
independentComponents
A sequence of Ints specifying the list of independent components that are included in
the definition of the connector elasticity data. This argument is applicable only if
*behavior*=NONLINEAR and *coupling*=COUPLED_POSITION or COUPLED_MOTION. If this argument
is applicable, at least one value must be specified. Only available components can be
specified. The default value is an empty sequence.
components
A sequence of Ints specifying the components of relative motion for which the behavior
is defined. Possible values are 1 ≤≤ *components* ≤≤ 6. Only available components can be
specified. The default value is an empty sequence.
