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.
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 Rayleigh damping ratio r (as in: R = r * K ), to do: also mass-proportional term.
double GetBeamRaleyghDamping ()

void SetDrawShape (std::shared_ptr< ChBeamSectionShape > mshape)
 Set the graphical representation for this section. More...
std::shared_ptr< ChBeamSectionShapeGetDrawShape () const
 Get the drawing shape of this section (i.e.a 2D profile used for drawing 3D tesselation and visualization) By default a thin square section, use SetDrawShape() to change it.
void SetDrawThickness (double thickness_y, double thickness_z)
 Shortcut: adds a ChBeamSectionShapeRectangular for visualization as a centered rectangular beam, and sets its width/height. More...
void SetDrawCircularRadius (double draw_rad)
 Shortcut: adds a ChBeamSectionShapeCircular for visualization as a centered circular beam, and sets its radius. More...
void SetCircular (bool ic)
 OBSOLETE only for backward compability More...
