bearing crush and hoop stress calculation
The Thinwalled Pressure Vessel Theory
Tangential stress in a thinwalled spherical pressure vessel () This tangential stress accounts for the stress in the plane of the surface of the sphere. The stress normal to the walls of the sphere is called the radial stress, r. The radial stress is zero on the outer wall since that is a free surface.

Engine Terms Imperial Club
The main and connecting rod bearings of a gasoline engine are each formed of two halfcircle sections which are assembled together to form a complete, circular bearing. Bearing Crush When journal bearings are assembled, each insert installed either in a semicircular bore in the block (or rod), or a similar area of a bearing cap.
