Analysis of Shear Stress and Bending Moment of a Bolted Joint

This paper investigates the shear stress and bending moment of bolted joints made of different materials. The introduction discusses the importance of bolted joints in mechanical engineering and the factors that affect their performance. The literature review presents the theoretical basis of bolted joint analysis and design considerations, as well as factors that affect working load in bolts. The study expands on previous work by examining the performance of bolted joints made of steel, aluminium 6061, titanium, cast iron, and nickel-copper alloy. The results show that the shear stress and bending moment values vary significantly depending on the material used. The highest shear stress values were observed in steel and cast iron, while the lowest were observed in titanium. The bending moment values were highest in cast iron and lowest in aluminium 6061. The results also show that the factor of safety for all the materials was 15, indicating that the joints were safe for use under the given loading conditions. The study contributes to knowledge by providing insight into the behaviour of bolted joints made of different materials. The results suggest that designers should carefully consider the material properties of bolts when designing joints to ensure optimal performance. For example, joints made of steel or cast iron may be suitable for high-stress applications, while those made of titanium may be more appropriate for low-stress applications. Similarly, the use of nickel-copper alloy may provide a good balance between strength and flexibility. In conclusion, this study highlights the importance of selecting appropriate materials for bolted joints in mechanical engineering applications. The results show that the shear stress and bending moment values vary significantly depending on the material used, and designers should carefully consider these factors when designing bolted joints. Future work could investigate other factors that affect the performance of bolted joints, such as joint geometry, tightening torque, and surface roughness.
