Springs are mechanical devices that are capable of storing mechanical energy because of their elasticity.Springs are often made of coiled, hardened steel, although non-ferrous metals such as bronze and titanium and evenplastic are also used. There are various types of springs, the designs of which take advantage of different energy storagemanagement. Springs are usually made of hardened steel that are formed into the shape of a helix which returns to itsnatural length when unloaded.Shot peening is done on the helical spring, which serves to increase the life of the component subjected to highcyclic stresses. These springs have been modelled and analysed using ANSYS 14.5 version.These springs have been manufactured and one of the springs of each material has been shot peened. Thesesprings are tested on Universal Testing machine for their deflection when subjected to different loads. It is observed thatthe spring that has been shot peened undergo less deflection for the same load applied when compared to spring tonormal spring.Spring steel is material used to manufacture. These materials have high yield strength and high ultimate strengthbut yield and ultimate are very close like brittle material but with high tensile strength.
