2009-4-3  RE: Crush strength calc for short steel member. Bribyk (Mechanical) 2 Apr 09 09:25. Local buckling of the tube wall, like crushing a pop can, may be your failure mode. The numbers sound high but, assuming a 50ksi yield strength, your tensile yield load would be about 162 kip and, if it doesn't buckle locally, it should hold more in compression.

Ring Crush Test Determining the Ring Crush Strength ...

2021-10-21  The ring crush test is similar to the short-span compression test in that the strength of the liner or fluting is measured both in the machine direction and perpendicular to it. It is important that force application to the specimen is exactly perpendicular during these tests. The results of this test are highly dependent on proper specimen preparation.

Bolt Torque Preload Calculator MechaniCalc

Due to preload uncertainty, the actual preload applied to the bolt may be more or less than the nominal value. Due to preload relaxation, there will be some loss in the preload after the joint is installed. The maximum value of preload accounts for the preload uncertainty, and is calculated as: F PL.max = (1 + % uncrt ) F PL.nom =. 533.0 lbf.
