Fatigue testing

Fatigue testing

Fatigue testing

(OP)
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?
