WebNov 24, 2024 · The bearing stress is a type of stress related to compressive normal stress that a body experiences whenever it is in contact with another body in equilibrium conditions. However, bearing stress is a special term that applies to elements in an object that bear a load – those that support or hold another part. ... A common example is a bolt ... WebApr 1, 2014 · The paper focuses on the bearing stresses in single bolt connections. Such connections with bolt in bearing present a basic connection component of a multi-bolt connection. The presented topic was extensively studied in the second half of the previous century [1], [2], [3]. Application of high strength steels opened new issues in the topic [4 ... gold frame clear glassesWebSep 8, 2015 · 5. Bolt shear is a limit state for the bolt, whereas bearing stress is more a limit state for the connected plates. Therefore, it makes sense to evaluate bearing stress on a plate-by-plate basis. When two or more plates are sharing the load, you can consider the total thickness in each loaded direction versus the total applied load. headache when smoking weed
