Bonnet is main component of a car at the front portion. It is used to decorate the car and add luxurious look. The shape of the bonnet is made aerodynamic in order to minimize the air effect. Bonnet is generally used to access the parts easily such as radiator, engine and many other parts. In automotive world the weight optimization plays an important role. In this paper material changes is applied to the bonnet for the same design and finally showing the stiffest bonnet and less weight component. For designing the hood 3D model CATIA V5 R19 is used, then import the cad model in to hypermesh and pre-processing is done using Hypermesh, solver is Optistruct Fea which helps to do the analysis for hood. For results visualization Hyperview and HyperGraph is chosen

Keywords: Hood, steel AISI 1045, Aluminium 6061, inner panel, outer panel, hypermesh
