PROBLEM FORMULATION 

The objective of this study is to analyze the structural performance of a unibody bicycle frame under a range of realistic loading conditions using the Finite Element Method (FEM). The analysis focuses on evaluating the frame's stress distribution, deformation behavior, and fatigue life when subjected to forces such as rider weight, road impacts, and aerodynamic loads.

This study aims to identify potential weak points in the frame's design that could compromise its structural integrity or performance. By leveraging FEM, the research seeks to optimize material usage for lightweight efficiency while maintaining durability and safety. Furthermore, the insights gained will contribute to ensuring the bicycle frame's reliability under diverse cycling scenarios, ultimately enhancing its overall design and performance.
