chrono::fea::ChBeamSectionCable Class Reference

## Description

Simplified geometry for a 'cable' beam section in 3D, that is a beam without torsional stiffness and with circular section (i.e.same Ixx and Iyy properties).

This material can be shared between multiple beams.

## Public Member Functions | |

void | SetArea (const double ma) |

Set the cross sectional area A of the beam (m^2) | |

double | GetArea () const |

void | SetI (double ma) |

Set the I moment of inertia of the beam (for flexion about y axis or z axis) Note: since this simple section assumes circular section, Iyy=Izz=I. | |

double | GetI () const |

void | SetDiameter (double diameter) |

Shortcut: set Area and I inertia at once, given the diameter of the beam assumed with circular shape. More... | |

void | SetDensity (double md) |

Set the density of the beam (kg/m^3) | |

double | GetDensity () const |

void | SetYoungModulus (double mE) |

Set E, the Young elastic modulus (N/m^2) | |

double | GetYoungModulus () const |

void | SetBeamRaleyghDamping (double mr) |

Set the Raleygh damping ratio r (as in: R = r * K ), to do: also mass-proportional term. | |

double | GetBeamRaleyghDamping () |

void | SetDrawThickness (double thickness_y, double thickness_z) |

Sets the rectangular thickness of the beam on y and z directions, only for drawing/rendering purposes (these thickenss values do NOT have any meaning at a physical level, use ChBeamSectionBasic::SetAsRectangularSection() | |

double | GetDrawThicknessY () |

double | GetDrawThicknessZ () |

bool | IsCircular () |

Tells if the section must be drawn as a circular section instead than default rectangular. | |

void | SetCircular (bool ic) |

Set if the section must be drawn as a circular section instead than default rectangular. | |

void | SetDrawCircularRadius (double draw_rad) |

Sets the radius of the beam if in 'circular section' draw mode, only for drawing/rendering purposes (this radius value do NOT have any meaning at a physical level, use ChBeamSectionBasic::SetAsCircularSection() | |

double | GetDrawCircularRadius () |
