Is yielding allowed in gears?
(OP)
The codes of practice for bending and pitting do not mention whether the permissible stress is calculated for the yield strength or the ultimate strength of the material. Do you know any resources that explain this please?

If your gear exceeds yield stress, then it will plasticly deform, changing your tooth profile.
This is aside from anything else that might happen.

Since fatigue limit is the main deign check for gears, why is it very important to include the yield and tensile strength of the material in gear design software?
