Hertz (Contact) Stress
Hertz (Contact) Stress
(OP)
I am designing the roller wheels for a bulkhead. By geometrical limitations the resultant hertz stress is 294 ksi. I am using Cast steel of fy=115 ksi. So the ratio is hertz/fy=2.6.
Where could I find an allowable Hertz stress (static loads)?
Hertz stress= ??? x fy
Where could I find an allowable Hertz stress (static loads)?
Hertz stress= ??? x fy

Is is Tensile or Yield?
My guess is it is 1.81 time
ultimate tensile strength.
