LocalStress.2d: LocalStress.2d

In FEA: Finite Element Modeling for R

LocalStress.2d

Description

Calculates local stress and strain for triangular elements of the mesh

Usage

LocalStress.2d(meshP, meshT, Y, Nu, GlobalND)

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.
Y	Value of Young's (Elastic) modulus
Nu	Value of Poisson's ratio
GlobalND	Global nodal displacement, return from function NodeDis

Value

Completes FEM by calculating values of stress and strain, produces three (3) [3 x n] matrix.

Strain	Calculated strain. [x, y, tau]
Stress	Calculated stress in pascals. [x, y, tau]
StressStrain	Stress as calucated from strain. [x, y, tau]

Examples

data(triMesh)
data(displacN)

meshP = triMesh$MeshPts$p
meshT = triMesh$MeshPts$T
Y = matrix(20e9, nrow = NROW(meshT))
Nu = matrix(0.45, nrow = NROW(meshT))
GlobalND = displacN$GlobalND

fea_result = LocalStress.2d(meshP, meshT, Y, Nu, GlobalND)
