I am producing the part for a customer. The geometries are similar between the parts. My issue is that these are aircraft engine parts and the substantiation requirements are very strict. Determination by comparison is not the best means of substantiation. I have considered doing a surface stress analysis of a new OEM part to determine the intensity but this would be difficult and the results may not be difinitive. I have found tables that show standard practice intensities but my application always seems to fall of of the chart. Low intensities of 6N on substrates like inconel do not make it on to the chart. 6Ns are typical for aluminum but not high tensile steels. Is there a MIL or AMS that I can reference that would have tables that inlude an application like this.
