Does anyone know of a standard or how to calculate the hoop stress caused by bearing crush. Thanks for your help.

Bearing Crush and Hoop Stress Calculation???

RE: Bearing Crush and Hoop Stress Calculation???
Stress = E x strain

-- Contact pressure calculation --
After several days of research, to calculate the bearing crush contact pressure, you can assume an interference fit pressure calculation of a bushing being press fit in a hole of smaller diameter. If anyone is interested I can explain further.

new bearing OD = 2.9980
change in diameter = 0.0020/3.0000 = 0.00067 inches/inch
E steel = 30,000,000 psi
Stress = E x strain
stress = 30,000,000 x 0.00067 = 20,000 psi
using circumferences would be proportionally the same.
Note bearing insert/race section area does not enter into it, but would determine how hard the bolts must squeeze to just close the housing's parting face gap
