Showing interest is nice, accusing people is not. So, show interest, something like "
I saw your article XXX in YYY and I am working on something similar. I was wondering how exactly you dealt with ZZZ."
But in a
first mail to the author(s) I suggest asking questions that
can be answered fairly simply/quickly and don't ask for too much. If it seems like it will be a lot of work to reply, then
you might not get any answer. You can always follow up with additional questions if the authors seem open to communication.
In the best case it can open the possibility of future collaboration if the topic is of mutual interest
So long as what you write is not rude or arrogant, nobody will care much.
The important thing is to ask some
specific questions.
If you just asked me for "details of methodology" I would hit the delete button, because I'm not going to write a comprehensive reply that is probably longer than the published paper telling you every little detail about what I did - especially if the paper was published years ago and I have forgotten most of the details anyway
