Bearing stress is the contact pressure between the separate bodies. It differs from compressive stress, as it is an internal stress caused by compressive forces.
The bearing stresses exerted by the clevis against the bolt appear on the left-hand side of the free-body diagram and are labeled 1 and 3.The stresses from the bar appear on the right-hand side and are labeled 2. The actual distribution of the bearing stresses is difficult to determine, so it is customary to assume that the stresses are uniformly distributed.

While there are several different types of stresses, tensile stress, and compressive stress are the easiest to understand. Tensile stress occurs when a force pulls or elongates the material, while compressive stress occurs when a force compacts the material. Figure 1 below illustrates these phenomena:

Correspondence between axial strain, deviatoric stress, volumetric strain, and permeability. ①. There is a good correspondence between stress-strain, volumetric strain, and permeability, and the variation pattern of the other two can be inferred from one of them. ②. Strain hardening - volume contraction - decreasing permeability. ③
For example, in fretting fatigue the peak tensile stress causes mode I SIF higher than the threshold even at small size of the crack, and the minimum difference between Δ K I and Δ K th is reached at the El Haddad crack size itself [63], [64], eventually producing initiated non–propagating cracks for loading conditions below the fatigue limit.

It is taken into account in the design of riveted joints, cotter joints, knuckle joints. Explanation:
Bearing (or Crushing) Stress of a Rivet.

Bearing stress refers to the contact pressure between two separate bodies. To visualize this, imagine a bolt thrust through a plate. The bolt applies a force to the plate, which exerts an equal but opposite force back onto the bolt. This force isn't just a singular entity but a compilation of numerous smaller forces distributed across the ...
