The document discusses the finite element analysis (FEM) of connecting rods made from various materials, focusing on their design and optimization for use in automobile engines. The study uses Pro/Engineer and ANSYS software to model and analyze the performance of connecting rods made of stainless steel, aluminum alloy, and high-strength carbon fiber, aiming to compare their stress and strain characteristics. The results are intended to assist in reducing weight and enhancing the lifespan and performance of connecting rods in automotive applications.
