WebOct 5, 2024 · Bearing stress in Bolts. Consider the arrangement shown below. It consists of a bolt, clevis and plate. Since, the clevis and the plate press against the bolt, the bolt will be acted upon by forces 1,2,3 (as shown). There is something called as bearing stress which will act on the bolt in this case. I don't exactly get what is this bearing stress. WebBearing Stress. 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. σ b = P b A b.
