The tendency of the metal to regain its original shape will result in the spring back when it is being formed to make aircraft components like outer body panels and brackets. When spring back occurs, the components will not meet the requirements of the design and there will be a need for shims to fit the component into place. This will lead to increase in weight, fabrication cost and also the assembly line time. So the Finite-Element Analysis (FEA) is used to accurately predict this deflection so that manufacturing processes can be optimized to produce a perfect output with least deviations from the design. This thesis bridges a relation between the experimentally evaluated spring back and FEA calculated spring back. Also in order to validate the FEA Analysis regression analysis has been performed. Variations have been tabulated and graphed as it bridges the gap between experimentally evaluated spring back and analysis of the design. INTRODUCTION Aircraft construction involves a wide range of materials. Out of these sheet metal plays a major role. Sheet metal aircraft construction is the most prevalent aircraft construction material by all measures, used extensively from jetliners to light, single engine airplanes and kits over the past five decades. Furthermore, virtually all other aircraft types use sheet-metal construction to some degree whether an instrument panel on a composite aircraft, or a firewall on a wood or steel tube and fabric design. New and modern metal alloys and materials have allowed aviation technology to advance, and is the reason it continues to dominate over other aircraft building methods. Steel’s and Aluminum’s unique combination of properties makes it one of the most versatile engineering and building materials in existence: Low weight / high strength relationship. Corrosion resistance, especially with newer alloys and modern primers. Low cost and widespread availability. The Bending process is the forming of sheet metal where angled or other shaped parts are produced. The process involves the uniform straining flat metal sheets around a linear axis, but it also may be used to bend tubes, drawn profiles bars, and wire. In bending, the plastic state is brought by a bending load. In fact, one of the most common processes for sheet metal forming are bending, which is used not only to form pieces such as L, U or V-profiles. Bending has the greatest number of applications in the automotive, aircraft and defense industries and for production of other sheet metal products. Typical examples of sheet-metal bends are illustrated in Fig 1. The basic characteristic of bending is tensile elongation on the outer surface and compression on the inner surface as shown Fig 1. Fig 1: Typical examples of sheet metal bend parts. The entire stress-strain curve is transverse, elastic stresses result in spring back and the residual stress pattern. Here, the bend radius Ri is measured on the inner surface of the bent piece. The bend angle
