    Design Phases/Stages - Order & Explanation

    What if we are trying to develop something like a ship or a plane? Or at least an aircraft engine? I mean some sort of heavy machinery... I believe there is a well established practice with well defined stages, is not there?

    Bolted Flange Joints: Studs vs. Bolts

    I looked through ASME B18.12 Glossary of Terms for Mechanical Fasteners. Very simillar to what is given in WIKI. So ASME is nothing to you? It is not an authority at all in the U.S. and can be avoided? What standards do you use? BTW, if I do what you say with our Russian GOST, I will be...
