Sorry for the long silene and thanks for both replies. Basically what I am trying to do is automate the connections between holes, mimicking the bolt connection, as shown on the picture.
The sequence of doing that, at least in my mind would be the following
1. Establish the Reference point...
Hello,
Although my proficiency in Python is limited, I would greatly appreciate a simple script that can verify the edges of assembly instances and generate a central reference point. With this tool, I can easily create multiple connectors in a large assembly.
Thank you very much.
Thanks, TGS4. I prepared the sheet and it is actually pretty straightforward.
Thanks for also explaining the shell vs solid element use. I have a good idea of when shell would be appropriate, I just wanted to see if there are some specific rules.
I have another question with regard to the...
Thanks, TGS4. Yes indeed I checked and I quoted the 2013 edition, but I do have a 2019 edition as well.
I am starting to see the advantage the elastic-plastic approach has over the elastic or limit load. The factor of 2.4 might seem extensive but the plastic limit stores a lot of strain energy...
Hi there,
I have another question with regard to the ASME Section 8 Dev2 PArt 5. For the calculation of protection against collapse, we have three methods: Elastic stress; Limit load, and Elastic-plastic stress. Since I have good experience with nonlinear FEA I would like to perform...
Thanks to both. Yes, I found the Becht Engineer "ASME SEC. VIII, DIV. 2 – PART 5, DESIGN BY ANALYSIS" but I just missed it in October and it seems it will not be on until spring of 2023, which is a bit late for me.
I will also change the title so more people can respond.
Thanks!
Hi there,
I am a CAE engineer and have been specializing in FEA for the past 10 years now. While I can get around analysis quite well I have not used it a lot in alignment with particular standards. I now have the opportunity to work in pressure vessel design and analysis and would like some...
Hi there. I am trying to define the seismic load using the ASCE 7. I have some troubles defining the "Ss" and "S1" parameters for my location (London)
Many thanks for help,

Yes, so we would also not run it at 3kW for longer than a few seconds, so I don't see the thermal part as an issue.
I am more curious if there are any motors in the same price range that are at higher voltage loke 220V?
Hi guys and thanks for help. We want to go for the BLDC because of the high power density. The motor has to be approximately 100mm x 80mm in dimension, similar to this one...
HEhe, no one is getting killed just yet. I was just exercising the thought if that would be possible. There is an application where conventional commutator motors are not applicable and I was having a thought of using a BLDC:
Hi! I am trying to use the BLDC motor in home appliances and I wondering if there is a simple way of running a BLDC motor (1.5kW) from a 220V AC grid.
To my limited knowledge, I would need an AC-DC converter and an ESC to create the three-phase for the BLDC. While ESCs are rather affordable...
Hi there, does anyone have any good proposal for the carbon fiber threaded inserts. I found the ones on the link below, but they are hard do get in my country.

Thanks for all the answers. I can see that the debate has gone a bit off. In the meanwhile, I have found an appropriate and tested coating that should protest the tank against ethanol.

Maybe someone needs this info at any point...
Hi There,
we are developing the carbon fiber fuel tank for vehicle application. We are worried about the chemical resistance of the CF tank. The tank would be made for the USA market, where gasoline can contain up to 15% of ethanol. I have come across some articles that the presence of ethanol...
Hi there and thanks to everyone for such extensive help.
I really like the solutions By Latexman and I would be happy to go with this solution. I have a few questions though.
1. How are such parts manufactured? Welded sheet metal?
2. How do we assure the even flow through each of the pipes...
Hi there,
I would like and opinion what would be the easiest way to split the flow coming form a single pump (160 m3/H) and even flow in 8 pipes (each 20 m3/h). the split into smaller pipes is needed for the water treatment that can only be made on the 20m3/h flow and we would like to avoid...
Hi guys and thanks again for the effort.
Do you think having a 2mm chamfer as a preparation for the filled weld would be reasonable?
Sorry for the confusing figure before.
Hi guys,
thanks for the extensive replies. This has been most helpful. If I try to summarize the suggestions, it would be better to have the option with the short screw.
If possible the best way would be to weld an additional cylinder on both sections as in the figure below. This would provide...
Hi there,
could someone provide some general guidance on how to bolt together multiple hollow sections? I am using only rectangular sections.
Also, I attached the figure below and am interested in which of the two ways is the "correct" one, when it comes to connecting two rectangular sections...
