To reduce the weight of the connecting rod of a vehicle's engine, the accurate buckling estimation is used as a major valuation basis. This study improves the previous efforts, based on finite element analysis, to include experimental results and accurate geometrical conditions. The critical buckling stresses of connecting rods which were cut off shank portion with various slenderness ratios, were estimated using the rig device which was made in this lab. Also the finite element model was improved by addition to the geometrical contact condition on the basis of experimental results. Hence this result indicates that the buckling prediction through FEA is more effective method than the classical formula.
