Application of Finite Element Method in Engineering- A Brief Review

Abstract

Finite Element Method (FEM) is a numerical method of stress analysis having large complexities of the
problems like, varying shape, boundary conditions and loads. It is also powerful technique for stress analysis in
aircraft, large machine body and large structural elements. This paper reviews the recent development of FEM and its
application in science and technology fields for sustainable and computerized development of engineering fields. In
this method the whole elements are divided in to various elements with numbers of nodes and calculation and
analyzed separately and designing it. The high performance computing facilities and advanced finite element
programs are now available for research and development activities in many universities in collaboration with
industries. Basically STAAD.Pro, GT STRUDEL, NASTRAN, NISA and ANSYS etc. computer software are used for
analysis and solving the many complex structures. Now days this method is used not only for the analysis in solid
mechanics, but even in the analysis of fluid flow, heat transfer, electric and magnetic fields and many others. In civil
engineering, this method extensively for the analysis of beams, space frames, plates, shells, folded plates, foundations,
rock mechanics problems and seepage analysis of fluid through porous media. Both static and dynamic problems can
be handled by finite element analysis. This method is also used extensively for the analysis and design of ships,
aircrafts, space crafts, electric motors and heat engines.
