ElementMat.2d: ElementMat.2d

In FEA: Finite Element Modeling for R

ElementMat.2d

Description

Generates an element stiffness matrix

Usage

ElementMat.2d(meshP, meshT, Nu, Y, Thick)

Arguments

meshP	Matrix (2 x n) containing coordinate points of the mesh nodes.
meshT	Matrix (3 x n) containing the number of the coordinate point that forms a given triangle within the mesh.
Nu	Value of Poisson's ratio for each element
Y	Value of Young's (Elastic) modulus for each element
Thick	Value of the thickness of the mesh, a positive value must be given.

Value

Generates initial element matrix needed for the finite element model.

EMPStress	An element matrix of the geometry under stress.
EMPStrain	An element matrix of the geometry under strain.

Examples

data(triMesh)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
Y = matrix(20e9, nrow = NROW(meshT))
Nu = matrix(0.45, nrow = NROW(meshT))
Thick = 0.001
DOF = 6

fea_EM = ElementMat.2d(meshP, meshT, Nu, Y, Thick)
