3. Conclusions This study aimed to assess the structural integrity of a titanium bicycle frame using finite element analysis, under a loading condition based on BS EN ISO 4210-6 standard. The results revealed very high von Mises stresses and absolute maximum principal stresses in the regions of the top and down tubes near the head tube. These findings indicate potential areas of concern for the structural integrity of the frame under the applied loading condition, even if the welds connecting the tubes were not simulated in the described model and could slightly influence the stress distribution in these areas. Further investigations, including the consideration of weld effects, are necessary to refine the analysis and more accurately predict the behavior of the frame under the considered loading condition. The use of uniaxial strain gauges in some points of the frame would allow for the experimental validation of the created finite element model.
