Bearing pressure - Wikipedia

Bearing pressure is a particular case of contact mechanics often occurring in cases where a convex surface (male cylinder or sphere) contacts a concave surface ( cylinder or sphere: bore or hemispherical cup). Excessive contact pressure can lead to a typical bearing failure such as a plastic deformation similar to peening. This problem

Stresses Due to Interference Fit Bushings - US Airforce Stress …

Stresses Due to Interference Fit Bushings. This post is taken from our free textbook “Analysis and Design of Composite & Metallic Flight Vehicle Structures” and defines a method for calculating the stresses due to an interference fit bushing. The method in this section is referenced to (AFFDL-TR-69-42, 1986) Section 9.16.
