1 CHAPTER 9 FINITE ELEMENT MODELING The finite element method is a very powerful tool for modeling and analysis of various structures (aircraft, spacecraft, launch vehicles, engines, automobiles, bridges, buildings, machine components) with complicated geometry. The finite element method transforms a structure into a system with a finite number of degrees of freedom (DOFs). In this chapter, we will consider finite element modeling and analysis of slender structures under uniaxial load, torque or bending loads. This will help us understand the fundamentals of the finite element analysis, while keeping the number of degrees of freedom small.
