At the heart of the VDI 2230 methodology is the (also known as the compliance or deformation diagram). This visual and mathematical model plots force against deformation for both the bolt and the clamped parts.

When a bolt is tightened, it stretches elastically like a stiff spring. Concurrently, the clamped components compress. The joint diagram plots these two opposing spring rates: The elongation per unit of force. Resilience of the clamped parts ( δPdelta sub cap P ): The compression per unit of force.

The VDI 2230 Part 1:2015-11 (PDF) is essential for engineers needing to:

Checking if the alternating stress amplitude under cyclic loading is lower than the thread’s endurance limit.

Select the final bolt size and strength grade (e.g., 8.8, 10.9, or 12.9). Verify the bolt is safe against yielding during assembly.
