This presentation provides an introduction to finite element analysis (FEA). FEA is a numerical method for solving systems of equations that model physical systems. It can handle complex geometries and loadings. The presentation discusses the pre-processing, meshing, and post-processing steps of FEA. It also describes one-dimensional, two-dimensional, and three-dimensional elements, how they have developed over time, their applications, degrees of freedom, and solution methods. Finally, examples of commercial FEA software are listed.
