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 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.
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...
