Detailed Description

A bond XBeam that works in tension, compression, bending and torsion very similar to the Beam bond.

The difference between Beam and XBeam is that XBeam uses a FEM formulation. So, XBeam can be used in FEM problem and it could advantageous speed-up a lattice calculation in comparison with the standard Beam.

Constructor & Destructor Documentation

◆ XBeam() [1/5]

GranOO3::DEM::XBeam::XBeam	(	Element &	el1,
		Element &	el2
	)

constructor

Parameters

[in]	el1	: the first bonded element
[in]	el2	: the second bonded element

Builds a new XBeam between the Element el1 and el2. Mechanical attributes are set to zero.

◆ XBeam() [2/5]

GranOO3::DEM::XBeam::XBeam	(	Element &	el1,
		Element &	el2,
		double	young_mod,
		double	radius,
		double	poisson_ratio,
		double	max_stress = `0.`
	)

constructor

Parameters

[in]	el1	: the first bonded element
[in]	el2	: the second bonded element
[in]	young_mod	: the Young's modulus of the beam in [Pa]
[in]	radius	: the radius of the beam in [m]
[in]	poisson_ratio	: the Poisson's ratio value of the beam
[in]	max_stress	: the maximal stress threshold of the beam in [Pa] (note that zero means infinite strength)

Build sa new XBeam between the Element el1 and el2 with the required mechanical attributes. In case of continuum modeling, note that the max_stress is not the best way for managing fracture. You may prefer to use the stress computation (see the ApplyFracture PlugIn) which gives more accurate results.

◆ XBeam() [3/5]

GranOO3::DEM::XBeam::XBeam	(	Element &	el1,
		Element &	el2,
		double	young_mod,
		double	damping,
		double	radius,
		double	poisson_ratio,
		double	max_stress,
		bool	nl_geom = `false`
	)

constructor

Parameters

[in]	el1	: the first bonded element
[in]	el2	: the second bonded element
[in]	young_mod	: the Young's modulus of the beam in [Pa]
[in]	damping	: the damping factor (in the [0,1] range) which is expressed as the ratio of the critical damping
[in]	radius	: the radius of the beam in [m]
[in]	poisson_ratio	: the Poisson's ratio value of the beam
[in]	max_stress	: the maximal stress threshold of the beam in [Pa] (note that zero means infinite strength)
[in]	nl_geom	: a flag to speed-up the computation (for simulation with small strain, displacement and rotation)

Builds a new XBeam between the Element el1 and el2 with the required mechanical attributes. In case of continuum modeling, note that the max_stress is not the best way for managing fracture. You may prefer to use the stress computation (see the ApplyFracture PlugIn) which gives more accurate results. You can set the nl_geom flag to true if you know that your simulation will handle only small deformation, displacement and rotation. In such a case, passing true to the nl_geom flag can speed-up the computation.
