    Bending moment calculation

    Looks like I'm using preliminary and outdated revision of the document. I should buy a new one. Thank you, kellnerp! Now I have to setup my study properly... 1. How threaded connections are treated in COSMOS? For example, my frangible connection has threaded connection to flange? Should I...

    Bending moment calculation

    Here are some sort of results I got with static study and Newtons applied. But when I've noticed that ICAO requires a bending moment in J, decided to ask Engineers.http://i51.tinypic.com/2rzq6wk.jpg

    Bending moment calculation

    Thanks for your reply! Yep, I'm not familiar with mechanical engineering. But I was also confused with units provided by specification. Talking about specification, it's "Aerodrome Design Manual" Part 6 by ICAO. Paragraph 4.9.2 says: <...>The yield point should be no more than 38 mm above the...

    Bending moment calculation

    I have: 1. A flange with central hole. Anchored to virtual wall with foundation bolts. 2. A pipe inserted in the hole with one edge. 3. A loading applied to the other one. According to specification, if a bending moment of 100J is reached, no damage should be made to the pipe, but if a bending...

    Fuse simulation

    The destruction is not electrical, it's themal. When we talk about power electronics, there is also a electrical influence during arcing time. But in my case, arcing time is minimal. But if you know proven way to simulate fuse, don't hesitate to shear with us.

    Fuse simulation

    No. This is kind of my own research and the way to help my colleagues.

    Fuse simulation

    Hello everybody! I'm trying to simulate fuse for 180nm process using CFD software. Fuse is a piece of Al wire created with top metal and passivation opening above. I apply power dissipation to it and calculate time-temperature chart. The problem is that I can't determine the point when my...
