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.

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 ()
