beamNodeDis function

beamNodeDis

Calculates global nodal displacements of beam.

beamNodeDis(beamP, BCtran, BCrot, REM, NodeKnownL, ForceV)

Arguments

• beamP: Matrix (2 x n) of beam coordinates.
• BCtran: Boundary constraint for nodes to translate in x or y directions.
• BCrot: Boundary constraint for nodes to rotate.
• REM: Reduced element matrix, returned from function ReducedEM.
• NodeKnownL: data frame with constraint parameters applied to each node in the x and y directions. Formatted for use in reduced element matrix. Generated from ApplyBC function.
• ForceV: Reduced force vector matrix containing the model load parameters. Returned from function ForceVector.

Returns

Produces tables with new node coordinates that are produced by the geometry under an applied load. - NodeDis: Nodal displacement

• GlobalND: Nodal displacement in the global environment

• GlobalNDMatrix: Nodal displacement in the global environment as a reduced matrix

Examples

data(beamGeo)
data(beamFV)
data(beamREM)
data(beamBC)

ForceV = beamFV
REM = beamREM
NodeKnownL = beamBC

beamND = beamNodeDis(beamGeo$beamP, beamGeo$BCtran, beamGeo$BCrot, REM, NodeKnownL, ForceV)
