detailed study on materials used for automotive bumper beams has been carried out with the key objectives of identifying the key property requirements‚ the currently used materials and alternative candidate materials. This report presents a detailed analysis of their respective advantages‚ drawbacks and a comparative ranking of these materials. The best alternative material has then been identified and a suitable manufacturing process for the bumper beam (using the best alternative material) has been described

Engineering materials Choice of materials for a machine element depends very much on its properties‚ cost‚ availability and such other factors. It is therefore important to have some idea of the common engineering materials and their properties before learning the details of design procedure. Common engineering materials are normally classified as metals and nonmetals. Metals may conveniently be divided into ferrous and non-ferrous metals. Important ferrous metals for the present purpose
