Hi everyone. I've got a bit of a philosophical question regarding shear failure of bolted joints. It is often common practice in my industry to check whether shear tearout, fastener shear, or bearing stress is of concern in a design. However, the general understanding of the behavior of bolted...
Hi all.
I've got a rather simple question that I can't seem to find an answer to in Machinery's Handbook - although perhaps I'm just looking in the wrong sections. My understanding is that wood screws do not conform to the unified series thread form (i.e. UNC, UNF, etc.) since wood screws...
Hi all. I have been having a discussion with a colleague related to relative displacements in a random vibration analysis. Specifically, we use ANSYS for our analyses, and my colleague in the lab was recommending the relative displacement be calculated using the difference of the RMS...
Hi all. I've noticed an inconsistency in the Goodman equivalent stress as presented in Shigley's (10e) and was wondering if anyone could help me out in understanding it. The tenth edition of Shigley's provides an example (Example 6-12) for determining the Goodman equivalent stress for non-zero...
Hello all.
I've been doing some review on this forum and other sources related to stresses in shear pins and I've not come across a definite conclusion. As it relates to shear pins, what is the correct way to analyze for failure? Most of the sources I've seen have considered failure on the...
