I am starting work on structural durability area for after treatment systems and deal with Random Vibration and PSD profiles quite often. However there are few fundamental questions about PSD profiles that I could not get answer to after a lot of search on internet. So finally decided to write...

Thanks David, The explanations helped a lot. An extension to the original question is, is there a similar relation between 'particle velocity' and 'fluid velocity' ? Best Regards Saumya

While the sound waves travel in a medium, let's say a fluid, what is the difference between fluid pressure and acoustic pressure ? Are these entities same?

Thanks a lot Tim, This really helped. For damage factor, I was referring to fatigue life analysis where for the design to be safe, damage factor needs to be below 1. I am not sure if it is referred with any other name.Regards Saumya

Hello Folks, May be I am bring up the old topic again., but I've lost enough sleep over this topic. I understand that we use Von-Mises criteria for ductile material failure by comparing to yield limit and max principal stress is used to check failure for brittle materials. My question is bit...
