I don't have any links to, but the Euro fork testing standards are available (or were a few years ago) for the public to view. For a person skilled in math and mechanics (engineer...) to calculate the stresses the fork goes under during the tests shouldn't be too hard (and I am not that person). IIRC some of this data has been posted here and/or in other framebuilder's forums (and there have been quite a few over the last 25 years).

I tend to be far more seat of my pants and taking spoken word, written word and/or what is actually done by the masses as a giideline. I learned long ago that modern bikes are very refined in their designs and there's very little new to add to the mix. Andy
