cement bag
(OP)
have any one modeled a cement bag in a dyan analysis or any other analysis. What I am trying to do here is to drop a cement bag on floor and see the stresses of the floor.

RE: cement bag
Why a cement bag? Are you interested in the reaction of the floor? If so, why cement at 94 lbs/bag rather than say corn at 100 lbs/bag? Or, are you designing the cement bag and want to see if it fails in the drop? If so, how far does it fall and why that height?

RE: cement bag
A good place to start is with a static analysis of the floor with 2X the load to make sure the floor thick enough to hand the load without permanent deformation. Then move to Dyna. But I question the use of Dyna if you are not interested in the crush of the floor. If you are interested in the crush then there is much more to be said on setting up this analysis.
RE: cement bag
I think I would start by just using a single 20 node brick to model the bag with the right mass, with simple elasticity, damping, and yield. If your not interested in the bag, but just it's effect, I would probably go this route, but that's just me. I tend to be very stingy with elements.
