ABSTRACT
A connecting rod is a link which derives the rotary motion from the reciprocating motion of piston. Many
materials are used for connecting rod. Every material has its own advantages and disadvantages, and are used depending
upon the engine requirement, purpose of the engine and other factors that matter. In this paper, a connecting rod with
three different materials viz. SAE 1141 Carbon Steel, T651-7075 Aluminum Alloy & 4340 Billet Steel, have been
designed using CATIA V5 R20 and analyzed using ANSYS 16. Deformation, equivalent stress and equivalent strain of
the connecting rod for all the three materials were compared to the same loads.

1. INTRODUCTION
The connecting rod is the most important links in a reciprocating I. C Engine. It connects the piston to the
crankshaft and is responsible for the conversion of reciprocating motion of piston into rotary motion of the crank
which is obtained on the Flywheel [1]. Figure 1 shows a usual form of a Connecting rod. It consists of a long
shank, a big end, which is connected to the crank and small end connected to the piston with the help of gudgeon
pin. The cross-section of the shank, for high speed engine is generally chosen to be an I or H section and circular
for low speed engines. The connecting rod is one of heavy links in the engine. Obtaining reduction in weight and
bearing high pressure of the engine for the Connecting rod, and maintaining the cost in an affordable range is a
challenge for the engineers. Lighter weights will not only offer lesser inertia force, reduced vibrations and
decreased overall engine weight, but will also help economically and ecologically, consuming lesser fuel and
reduced emissions from the vehicle.
A lot of engineering materials have been developed for obtaining reduced weight for the same strength
and stress bearing ability Aluminum alloys, Steel alloys to mild carbon steels. The most common material for the
connecting rod is the Steel. Titanium and Aluminum Alloys are used for reduced weights. Generally, the
connecting rod is made through dropped forging, since it is a cost effective process. Connecting rods for
automotive applications are typically manufactured by forging from either wrought or powdered forged [2].
Different materials have their advantages and disadvantages. Some are maybe being lighter in weight, but are
