Not sure if this is relevant to your case, but I am using sigmacalx.com library for bolted structures where pressure is involved in testing equipment as a load.

Would probably be easy to check it using von mises criterion first. Your burst pressure is 36bar.

Hey, I came across some ACT extensions for Ansys that seem pretty useful. They cost a bit, though, but might be worth it if they save you time. Check them out here: https://www.sigmacalx.com/act_extensions

Hi I'm trying to find the best way to calculate the radial expansion of the pressure vessel with a variable length. Please take a look at the image I've for better explanation of my issue. I have three test cells that have the same dimensions with only length different. Identical internal...

Is anyone here who can share an Excel spreadsheet with fatigue calculation formulas based on ASME BPVC VIII-2 or -3

Thanks for a clarification, now I got it

Hi I've been asked to prepare a fatigue screening for ALLOY 718 / UNS N07718. I usually use ASME Part 2 to calculate allowable stress for fatigue screening but a client wants me to use API 17TR8, where allowable stress is found by 2/3 Sy. ASME gives me a value of 206MPa for N07718 but API 17TR8...

We were looked at the Bourdon tube pressure gauges. It would be a perfect solution but we are limited by the space we have. I attached the drawing we prepared for a spring manufacturers. We basically want to see on other solutions to replace that spring. We looked at the helical bourdon tube...

Thanks for your suggestion, I'll definitely look at it.

Hi there, I'm looking for some solid material that can change its shape or geometry under pressure. Let's say i have a solid piece of a sample with a diameter 10mm and length 100mm. The sample is placed in a pressure chamber and pressurised from 0 to 2000bar. Every 50bar the sample is being...

Basically the title is my question. I cant find the UNS equivalent to these two materials S420 Structural Steel and Strenx® 700 Structural steel I need to find the UNS equivalents for those two materials in ASME II Part D. Any help would be appreciated BR, Sergey

thanks [smile]

Thanks for the answer, Do i need to set any special material property to the model so it expends due to temperature because now it is only about 200C the max and after that it is no changes in results. Here is what i have for the material Isotropic Elasticity Multilinear Isotropic Hardening...

How can I simulate bolt pretension in this connection. Yellow and Green parts are tightened with 120Nm at the same time yellow part is pushing grey part towards green making a sealing connection in between. When the connection is tight I have to apply internal pressure to check that the sealing...

Hi folks how to actually find those connections. I got some warnings and really want to find them. The warnings are> *** WARNING *** CP = 157.422 TIME= 12:26:16 Contact element 59090 (real ID 31) status changes abruptly from contact (with target element 59018)...
