Examples of Finite Element Analysis

Earlier, the crash simulation of automobiles were carried out by experimentation, which was extremely costly & time consuming.

Crash Test of Automobiles:

Now-a-days, the same can be done using finite element methods, requiring minimum number of experiments to validate the results of the virtual simulation.
