Finite Element Analysis is basically taken into account during a new product design or in the modification of an existing one. Finite Element Analysis makes use of the computer models which are stressed and has been analyzed to receive the required results. FEA works with a structure of points called nodes which create a network or in other words a mesh. This mesh contains properties that will define the reactions during certain loading conditions and the nodes in the mesh are dispersed according to the densities and stress i.e. regions that hope to receive large stress will contain the nodes of higher density.

History of Finite Element Analysis (FEA)

FEA or Finite Element Analysis was initiated by R.Courant in 1943 which was later changed in 1956 according to the presentation made by M.J.Turner, R.W.Clough, H.C.Martin and L.J.Topp. Since then Finite Element Analysis saw changes and now the supercomputers can provide results accurately for all kind of parameters. It had earlier started off with the Ritz method on numerical analysis and minimization of variation calculus.

Analysis is done through two methods 2-D modeling and 3-D modeling. 2D modeling keeps up the simplicity and is also used in computers no matter how slow or fast. At the same time, 3-D modeling produces accurate output effectively but restricted to fast computers. Various functions can be added by the programmer which can make the system both linear and non-linear where linear is commonly found to be less complex while non linear takes into account the plastic deformation and bringing out the entire information.
