Introduction To FEA

The finite element analysis (FEA) is a computational technique that is used to obtain approximate solutions to the boundary value problems in engineering. In this analysis, a numerical technique called the finite element method (FEM) is used to solve boundary value problems. FEA involves a computer model of a design that is loaded and analyzed for specific results. The finite element analysis was first introduced by Richard Courant in 1943. He used the Ritz method of numerical analysis and minimization of variational calculus for getting approximate solutions to vibration systems. Later, the academic and industrial researchers created the finite element method for structural analysis.

The concept of FEA can be explained through a simple example of measuring the perimeter of a circle. To measure the perimeter of a circle without using the conventional formula, divide the circle into equal segments, as shown in Figure 11-1. Next, join the start point and endpoint of each of these segments by a straight line. Now, you can easily measure the length of straight line, and thus, the perimeter of the circle.

If you divide the circle into four segments only, you will not get accurate results. For more accurate results, divide the circle into more number of segments. However, with more segments, the effort required would be more. The same concept applies to FEA also and therefore, there is always a compromise between accuracy and speed while using this method. This makes it an approximate method.

The FEA was first developed to be used in the aerospace and nuclear industries where the safety of structures is crucial. Nowadays, the simplest of the products rely on the FEA for their design evaluation.
