I am trying to reconcile the considerable difference between the ASME S-N curves and what you find in typical machine design textbooks (e.g. Shigley).
In the texts (e.g. Shigley), S-N curves are constructed using S_ut. The endurance limit (N=10^6) is 0.5*S_ut for lower strength steels. The...
Anyone here work with 625 regularly that could comment on whether a microstructure we are seeing is normal/typical?
We have not etched yet and are using BSE and EDS on the SEM to differentiate phases in a polished specimen. We don’t have EBSD so the identification of phases is a bit loose. We...
Does anyone know where I can find documentation on how SOLIDWORKS calculates the transverse shear stress in beam elements. I am used to the tau=VQ/Ib formula.
SW appears to use a shear factor, but does not provide documentation on how the value is derived or used to calculate the maximum shear...
I am trying to analyze the stress in a simple link (straight link, pins at both ends) that is part of a mechanism (planar analysis).
I have solved the planar kinematics/kinetics equations (rigid body motion), so I know the reactions at the pins and accelerations (linear and angular) at the...
I understand the definition of the resultant condition (RC) for MMC and LMC, but what I fail to understand is how they are applied. A search of the 2018 revision found no hits for resultant condition outside of the table of contents and the figures in section 5.
Using an external feature at...
I am having a bit of confusion around how to interpret a feature that has both position and perpendicularity tolerances attached to it. I get that the position control will, by itself, restrict the orientation and my understanding was that an additional orientation control was only added if...
