Hi i am nabi. I am working with Dynamic Progressive crushing of Tube. I am looking for an equation of such case after crushing of tube with maximum UTS. Please refer me some equations or links or paper regarding this. Here i added some pictures as well as my DESIRED EQUATION'S HINTS.
Hi
I have never worked this topic but I know that it is part of the design for offshore structures, e.g. wrt accidential loads.
For equations, a good starting point is DNV RP-C204.
The general rule is to use Non Linear FE as equations only can take you so far, see DNV RP-C208.
Sincerely
Claes
There is some work from Abramowicz, who has developed (semi-) empirical equations for the estimation of crushing tubes:
