The standard treats the bolt and the clamped parts not as rigid bodies, but as elastic springs. This approach allows engineers to calculate the "load introduction factor," determining how much of an external load is absorbed by the bolt and how much is relieved by the clamped parts. The 2015 version (VDI 2230-1:2015) was the previous benchmark, but the rapid advancement in materials science and the push for lightweight design necessitated a revision that could offer higher calculation accuracy and reliability.
Let me know, and I will provide the exact section or formula you need.
