First of all thanks for the answers, I made a check to verify the steel hardness:
it is 192 HB (207 HV), having a tensile strength of 655MPa.
The Hertzian stresses I've found in the F.E.A. are very high,
but considering that I used a very fine mesh, I think that results could be realistic, (and...
Hello guys, I'm a new member of this forum and I'm trying to give an answer to this question:
what is the maximum allowable Hertz contact stress for a steel with 520MPa of yield strength?
Thanks to all.
