STRESS
The state of stress at any point in a loaded body is dened completely in terms of the
nine components of stress: xx , yy , zz , xy , yx , yz , zy , zx , and xz , where the rst
three are the nor

Finite Element Modeling for Bar Elements Using the MPE Principle
In this Chapter, we will systematically construct the finite element model for the bar element.
5.1 Strain energy for a bar e

Introduction
1.1
What is the finite element method
The finite element method (FEM) is a numerical technique for solving problems which are described
by partial differential equations or can
Chapter 4
Shape Functions
In the finite element method, continuous models are approximated using information at a finite
number of discrete locations. Dividing the structure into discrete elements is
Chapter 6
Finite Element Formulation for Trusses
We know that each element in the truss (see Figure 2a) can only take either a tensile or compressive axial
force. In that respect, truss elements are i
Chapter 2
The Principle of Minimum Potential Energy
The objective of this chapter is to explain the principle of minimum potential energy and its application in
the elastic analysis of structures. Two
STRESS
The state of stress at any point in a loaded body is dened completely in terms of the
nine components of stress: xx , yy , zz , xy , yx , yz , zy , zx , and xz , where the rst
three are the nor
Chapter 7
Finite Element Formulations for Beams and Frames
Beams and frames can take axial, transverse (i.e., perpendicular to the axis), and moment loads. Unlike
truss elements, they undergo bending.
Chapter 3
Rayleigh-Ritz Method
As discussed in Chapter 2, one can solve axially loaded bars of arbitrary cross-section and material
composition along the length using the lumped mass-spring model. As
