double	GetKsz () const

void	SetAsRectangularSection (double width_y, double width_z)
	Shortcut: set Area, Ixx, Iyy, Ksy, Ksz and J torsion constant at once, given the y and z widths of the beam assumed with rectangular shape.

double	GetGshearModulus () const

void	SetGwithPoissonRatio (double mpoisson)
	Set G, the shear modulus, given current E and the specified Poisson ratio.

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 thickness 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 ()
