As a mechanical engineer, ensuring the safety and reliability of structures is paramount. Throughout my career, I have worked on numerous projects that demand rigorous analysis, especially when dealing with critical mechanical components like bolts. In the realm of Finite Element Analysis (FEA), bolts are often subjected to complex forces and moments, and understanding their behavior under these conditions is essential for maintaining the integrity of the overall design.

When using simplified models with surfaces and beams, it's not feasible to include 3D bolts directly in the simulation. Instead, we simulate bolts using point elements that track the forces and moments within the bolt. This approach is also used to simplify 3D models, as calculating bolt strength using well-established analytical equations often yields more reliable results than relying solely on software simulations. Bolts can introduce stress concentrations and hotspots in simulations that may lead to misleading or erroneous results if not properly accounted for.

To streamline the bolt analysis process, I developed this bolt analysis tool. It is designed to calculate the stresses and strains on bolts based on FEA-derived forces and moments, providing a quick and accurate assessment of bolt performance under various loading conditions. By integrating this tool into my design process, I can ensure that all designs meet the required safety and performance standards before moving into production.

This tool helps prevent several types of bolt failures by analyzing key stress points, including:

• Shear Stress on the Bolt
• Tensile Stress on the Bolt
• Von Mises Stress on the Bolt
• Principal Stress on the Bolt
• Thread Stripping for the Bolt
• Thread Stripping for the Nut
• Bearing Stress on the Joining Plates
• Bolt or Nut Tearout from the Joining Plates
