Finite element analysis (FEA) is a computerized analysis method to envisage how a manufactured product will react to the physical world. The analysis includes bringing the product in contact with force, heat, vibration, fluid flow and other such physical conditions. The FEA can predict if the product is likely to break, tear, wear or behave the way it is manufactured to.
First developed in 1943 by R. Courant, finite element analysis is a part of the manufacturing process in order to help predict how an object would react to real-world conditions when used. FEA also helps solid-state scientists to improve the quality and function of an object. FEA essentially computes the individual component behavior and sums it up to predict the overall behavior of the manufactured product. FEA now commonly uses computers to model the object, which is then stressed and analyzed to obtain desired results. In the case of a faulty product or undesired result, FEA can help create a new design to meet the necessary conditions.
