Hi All,
I am new to space technology... I stumble upon the random vibration assessment criteria from a textbook that using yield strength when using a random load...
Why not fatigue strength as random vibration is a durability type of loading? P/s: not going into details to use Miner's rule etc.
In addition, what is the safety factor that used in space industry? My past experience in aerospace using 1.15 - 1.50 ... And the textbook (by J._Jaap_Wijker) suggesting the same... is that true?
Many thanks in advance!
