HI All:(adsbygoogle = window.adsbygoogle || []).push({});

Using Hertz contact formula I calculated contact stress for cylinder in contact with cylinderical socket but I dont know to which stress to compare this contact stress.Actally I comapred with material bearing stress & calculated stress was less that bearing stress(got margin of saftey 2), but I am not sure whether to comapre this with the baering stress so please some body tell me to which allowable stress to compare this contact stress.

Well to calculate the Hertz conatact stress i used the folowing formula.

stress=.591*SQRT(p*E/Kd)

And if I want to compare hertz stress with shear stress what wold be the relation between two.

thanks
