Good day,
This has been bothering me for a while:
The table attached is from the MIL-HDBK-5H.
We often specify heat treatment on these steels in the range of 125-145 KSI (usually purchased in the heat-treated condition) or 145-160 KSI (requires additional heat treating). Both these ranges are...
Hello,
I have a small cylindrical adapter D=2" L=8".
For the strength needed, according to MIL-HDBK-5H table 2.3.0.2, I should use 4340 over 4140 since 4140 has a maximum diameter of 1" for quenching & tempering.
The question I have is especially regarding material ductility.
I can establish...
Hello,
I have a very simple question: where do you get your material properties from, either for hand calcs or FEA?
So far, I've been using a combination of textbooks, Machinery Handbook and Matweb.
I would like to buy a single authoritative book for all the times I need a material property. I...
Hi everyone,
quick question for you:
Imagine we have a 1/2" diameter dowel pin/ground shaft, 2" in length, with the first inch press fitted in a steel 'immovable plate', and with the other inch horizontally sticking out, a la cantilever beam.
Assume the dowel pin carries a certain load...
Hi everyone,
see the image attached.
As you can see, there are 2 different assemblie.
The assembly on the left consists of just a single machined part.
The assembly on the right concists of two machined parts.
Both assemblies (ie. on the right and on the left) have the same over all...
Hi everyone,
I've been looking for an FEA software for some time now.
I do 3D design work in Solidworks (PRO, without the simulation add on - actually it has a lite 'express' version).
So far I've been checking my designs by hand, and I have used the trial version of Solidworks simulation and...

Hi guys,
I'm finally signed up as a member here on eng-tips. Been reading the forums for longer than I can remember, was great help through school and now graduated 1 year ago.
So I'd like to discuss about position tolerances of dowel pins.
For example, let's say we have Part#1 with two 0.250...
