NettetBearing 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. In a bolted connection, the role of the bolts is normally to press one parts on the other; the adherence (friction) is opposed to the tangent forces and prevents the parts from sliding apart. In some cases however, the adherence is not sufficient. The bolts then play the role of stops: the screws endure shear stress whereas the hole endure bearing pressure. http://www.ecourses.ou.edu/cgi-bin/eBook.cgi?topic=me&chap_sec=01.2&page=theory sprinkler tractor parts

NettetSee chapter J3-10; the maximum bearing stress depends on the consideration whether deformation at service load is allowed or not. But the minimum allowable is 1.2-1.5*σ ult (WSD; UF=0.6) or 1.8-2.0*σ ult (LRFD). See chapter J7; the max bearing stress allowed finished surfaces for WSD is 0.9*σ 0.2 (unity factor=0.6) and for LRFD 1.35*σ 0.2. NettetThe basis of the linear bearing stress ( bearing ) and bypass stress ( bypass ) concept presents the stress alongside the bolt hole in an infinite plate as shown in Fig. 6.

A tear-out commonly happens when a notch is placed to close to the edge of a material. Basically, what happens is a portion of the plate, right after the notch, gets torn out due to …

NettetSince 1991, bearing stress has been based on test results at a yield limit state, which is defined as the 5% diameter offset on the load–deformation curve. The bearing stress … NettetSince 1991, bearing stress has been based on test results at a yield limit state, which is defined as the 5% diameter offset on the load–deformation curve. The bearing stress at proportional limit load is largest when the bolt does not bend, that is, for joints with small L/D values. The curves of Figures 8–8 and 8–9 show the reduction in ...
