Abstract: The plan of the transport body depends to a great extent upon the execution necessities under different sorts of stacking and working conditions other than those of the street conditions. The body of Ashok Leyland Viking 115 is chosen. Their basic quality, strength, crash value and so on are scarcely assessed, bringing about diminished traveler wellbeing with expanded probability of harms. Thus, the first body is overhauled by changing the thickness and diminishing the quantity of components, so that, the aggregate weight of the transport is lessened. The present utilized material for structure is steel. It is supplanted with composite materials of fiber. The thickness of steel is more than that of composite materials, so by supplanting with composites, the heaviness of the structure is diminished. Auxiliary and dynamic examination is done on both the structures utilizing three materials to decide the quality of the structure. Investigation is done in ANSYS.
