VDI 2230 is a technical guideline that provides a systematic calculation method for concentric and eccentric bolted joints under tensile and shear loads. Unlike simplified structural codes, VDI 2230 treats the bolt and the clamped parts as an elastic system (frequently modeled using the joint diagram or "clamping triangle"). Scope of Part 1 vs. Part 2 Understanding VDI 2230 (2021): The Definitive Guide to

: Recent studies address a "scientific deficit" in standard VDI 2230 theory, which assumes atmospheric pressure. Research now explores how high hydrostatic pressure in deep-sea environments can cause up to 40% preload loss , leading to potential flange leaks . Part 2 : Recent studies address a "scientific

Tightening stretches the bolt, creating a clamp load.
