Abstract—In this study simulation is conducted on a model of connecting rod of a single cylinder four stroke engine. The main objective of this paper is to develop a new insight for the use of composite material in connecting rods. Finite element analysis was done to compare the conventional isotropic material and the orthotropic Composite Material. Modeling of connecting rod was done using software CATIA V5 and for stress analysis it was imported to MSC. PATRAN. Linear static analysis was carried out for both isotropic material and orthotropic composite material with mesh TET4 to obtain the stress results. Comparison of both the material was done, keeping the boundary conditions “samefor” both materials. For future research, the same analysis can be done with the MESH TET10 and the same can be compared to obtain varied results.
