ExpandEM.2d {FEA}

ExpandEM.2d

Description

Generates the expanded element matrix, which represents the contribution of individual finite elements towards the global structural matrix

Usage

ExpandEM.2d(meshP, meshT, centroid, EMatrixlist)

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.

centroid

Matrix (2 x n) containing coordinate points of the centroid of each triangular element.

EMatrixlist

EMPStress or EMPStrain generated from ElementMat function. List of element matrices.

Value

Produces large (n x n) matrix.

ExpandedMat

The expanded element matrix

Examples

data(triMesh)
data(fea_EM)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
centroid = triMesh$Centroids
EMatrixlist = fea_EM$EMPStress

fea_ExEM = ExpandEM.2d(meshP, meshT, centroid, EMatrixlist)
