Finite Element Analysis in Automobile

Abstract

As the automobile industry is moving towards the production of lightweight materials, improved fuel efficiency and structural characteristics have become more significant. In the present study, aluminium and polymer composite materials are compared for producing automobile bodies according to simulations. Though used conventionally, aluminium is heavy and corrodes easily. In order to overcome the drawbacks mentioned above, polymer composites proved to be a more suitable choice since they are weightless, have satisfactory strength, and can resist corrosion. Simulation output shows the polymer composite is superior in many respects. It deforms much less with deformation reduction 66.2% and less strain, and hence it is stiff and more resistant to stretching on impact. It also withstands impact forces better, with less equivalent stress of 28.8% decreased. All these point towards polymer composites as a potential substitute for aluminium in car body manufacture, with increased durability and performance.
