Fatigue Failure Analysis of Connecting Rod of Different Cross-Sections

Abstract

Connecting rod is the link between piston and crankshaft which is acted upon by axial forces and moments
at its ends, and converts the reciprocate motion to rotary motion. Yield, fatigue and buckling phenomenon are considered
for the design and performance of connecting rod. The Finite Element Analysis is capable to give the results like stress,
fatigue life, strian, thermal analysis and deformations, throughout of the component subjected to complex loading. In the
present work, the fatigue life analysis is carried out by ANSYS using stress and strain life theories for different crosssections connecting rod. The equivalent Von-Mises stresses, Principal Stress and Shear Stress are calculated for (+)
section, (H) section and (I) section. Finally it concluded that I section connecting rod is best rest of two in all aspects.
