What are Hertz contact stresses?


I have read about the Hertz contact stresses, applied at bearings for example. I have never fully understood what is meant with it.

What is it that you don’t understand? The name or the equations (or both)?

The “Hertzian” contact stresses, or Hertz contact stress theory, is just called that because Hertz is the one who did the derivation. If you make the assumptions he made, and do the analysis for two surfaces in contact (his initial case was for two curved surfaces touching), you get the appropriate equations.
