The you must check:

Ensure the threads are long enough so that the bolt shank breaks before the internal or external threads strip out. This depends heavily on whether the female thread material is weaker (e.g., aluminum) than the steel bolt. Step 12: Verify resistance against sliding / shearing ( SGcap S sub cap G vdi 2230 2021

Determine the exact external forces acting on the joint: axial force ( FAcap F sub cap A ), transverse force ( FQcap F sub cap Q ), and bending moments ( MBcap M sub cap B Step 4: Estimation of Bolt Size (Trial Dimension) The you must check: Ensure the threads are

For the first time, the guideline includes a standardized XML data schema. This allows direct interoperability between FEA software (Abaqus, Ansys, Simcenter) and calculation tools (KISSsoft, BoltEx, MITCalc). No more manual transfer of spring stiffness values. Step 13: Check for embedding and relaxation (

If the joint experiences transverse (shear) forces, verify that the remaining clamping force multiplied by the interface friction coefficient is large enough to prevent parts from sliding. Step 13: Check for embedding and relaxation ( ΔFZcap delta cap F sub cap Z

), it ensures that no potential mode of failure is overlooked.

While modern Finite Element Analysis (FEA) is powerful, VDI 2230 remains indispensable because it provides a standardized, repeatable mathematical framework that FEA often lacks in the specific context of bolt-clamping physics. Key Calculation Steps in the 2021 Edition
