Since connecting rod is to subjected complex loading conditions, for which realistic stress prediction is a challenging task. Though the Finite Element Method (FEM) is widely used, but its results contain some inaccuracies that comes from various sources, out of them discretization error is considered to be major source. Present study aims to enhance FE solution accuracy through adopting newly developed Adaptive Mesh Refinement (AMR) technique. In present studydynamic structural behavior of connecting rod is evaluated through conventional and advanced AMR discretization technique. In this research analysis of connecting rod conducted for 1.3 second where cyclic loads have been applied within 13 sub steps at various crankshaft positions. It is observed through analysis results, that maximum stresses have been produced in connecting rod at shank and at big end during compressive and tensile loads respectively. While comparing results obtained from conventional and advanced AMR discretization technique it is observed that 15.7% increase in Von-Mises stresses was noticed by applying AMR technique during compressive loads. Whereas in case of tensile loading no effect was observed.
