Does anybody know of a standard procedure or theory for progressive applied fatigue testing? For example. Suppose I have a structure that I want to test for durability. I have several identical assemblies. I apply a static load to produce an ulitmate failure in one assembly. Then, I set up another assembly and apply...say 60% of the ultimate load over and over again for some number of cycles, but produce no failure. Then I increase the load by 10% and cycle for some other number of cycles. If I still produce no failure, I increase the load again and cycle for some number of "events". This continues until a crack is produced.
Anyway, I believe that there is a standard procedure for this, but I can't find it anywhere. Can anybody help me out here?
