I'm a ME student and I've been studying Machine Elements on this semester. One of the primary topics is Bolted Joints and I was interested to read up more on them. My professor teaches us outdated standards and it seems that the book he uses (the one he wrote) has no reference whatsoever to any other books. I'm in Europe so I am interested in ISO or DIN standards that would outline the calculation of a bolted joint. Also, a book or a guide with examples would be great.
