    .doc: """
    These properties define the flexibility and dissipation characteristics of the track system.

    The flexibility is defined through the track's resistance to various deformations:
    - Tensile: Stretching along the longitudinal axis
    - Bending: Rotation around vertical and lateral axes
    - Shear: Deformation along vertical and lateral axes
    - Torsional: Twisting around the longitudinal axis

    Each flexibility mode includes stiffness and attenuation factors.

    The internal track energy dissipation is defined through internal friction between track segments, see the damping and hinge_friction parameters.

    bending_rotational_range_min - The min rotational range of the connection between the links.
                                   This is rotation around the transversal axis.
    bending_rotational_range_max - The max rotational range of the connection between the links.
                                   This is rotation around the transversal axis. Note that if max <= min
                                   then no range is applied to the connection between the links.
    flexibility                   - Defines the stiffness properties for all deformation modes.
    damping                       - Defines the damping properties for all.
    enable_hinge_range            - Enable/disable the rotational min and max range of the connection between links.
    hinge_friction                - The internal friction in the node hinges.

    Example:
    In the example below we define the track flexibility and dissipation properties for a track system.
    The flexibility is defined using a linear elastic track flexibility model, and the dissipation is
    defined using a attenuation dissipation model.
