Finite Element Analysis (FEA) is a method of calculating engineering stress common with today’s computer aided design software. Finite element analysis works by using a computer to split the geometry of the body into a series of triangles. Each triangle has three equations associated with it that rely on input from the triangle next to it. Using a nice graphical interface the user will apply external loads and restraints to the body and in a cascading method, the computer will calculate how one triangle affects the triangles next to it and so on until it has completely resolved the analysis. The user also sets the resolution of the analysis by adjusting how physically large each triangle is which in turn affects how many triangles are in the analysis. A lower resolution has less triangles and runs faster but offers less accurate results as a high resolution analysis with many triangles. It is common for an FEA analysis to have millions of triangles and take several hours to run even on high-end computers. Output is generally communicated through a stress and deflection plot (that is well known for their rainbow colors) signifying large and small magnitudes in the analysis.
