Bearing Stress
Bearing Stress
(OP)
Hello everyone,
Is there a way to estimate the allowable bearing stress of a metal if the typical properties (UTS, YS, E, ect.) are known? I know the bearing stress is usually much higher than the yield, and a little higher than the UTS, but I would like to know for sure.
If this is not possible, where can I find this information? I cannot find it in my usual material properties sources.
Thanks

The info above is good for the condition defined by vonlueke. That kind of 'bearing strength' is largely empirical and is not a true Hertzian bearing strength. If you are concerned with any other kind of bearing, i. e., any kind of part bearing against any other part, the allowable usually depends upon design requirements. That is, bearing companies do not want spalling or other fatigue damage; railroads may be concerned with other kinds of failure, etc. Permanent set occurs, theoretically, at about 1.81 times TENSILE yield strength of the material, where stress is calculated by Hertz' methods. Hope this helps.
