SurfaceTraction.2d: SurfaceTraction.2d

Description

Element Surface Traction - generates the column matrix for uniformly distributed surface traction. If surface traction is not present, assign SFTensile and SFShear a value of 0.

Usage

SurfaceTraction.2d(meshP, SFTensile, SFShear, Length, Thick, area)

Value

List of element matrices containing surface forces.

SurfT

List of surface forces for each element.

Arguments

meshP

Matrix (2 x n) containing coordinate points of the mesh nodes.

SFTensile

Magnitude of tensile surface traction

SFShear

Magnitude of positive shear traction

Length

Truss length

Thick

Triangle element thickness

area

Triangle element area

Examples

data(triMesh)
data(dime)

meshP = triMesh$MeshPts$p
SFShear = 0
SFTensile = 0
Thick = 0.001
Length = dime$TrussLength
area = dime$Area

SurfTrac = SurfaceTraction.2d(meshP, SFTensile, SFShear, Length, Thick, area)
