WebThin pressure vessels are those for which the ratio of the least radius of curvature of the wall to its thickness is greater than ten. These thin pressure vessels are further subdivided into simple ones which are discussed in Section 8.3.1 and stiffened ones which are discussed in Section 8.3.2. Thick pressure vessels are discussed in Section 8.4. WebMar 25, 2024 · That will tell you how many bolts are needed to support the load + safety factor. Multiply the length and width of the steel plate to determine its area. The 0.57*TYS is probably taken from the von Mises/distortion energy/octahedral shear stress criterion, and it should be stated as shear yield strength = 0.577*tensile yield strength.
WebSep 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.
