Modelling a shock loading

[yvan]

I'm a french engineer in mechanics and i have to make the numerical model of an armchair travelling.
The problem is not in static, but in dynamic : i don't know how to incorporate shocks loading (against an obstacle, trottoir,...).
I use Catia5 (FEA module) and ansys (5.5) but i haven't got Ls Dyna.

What software should i use ?
How can i do ?

I suggested NE/Nastran for dynamic modeling. You can obtain an evaluation version from:

I hope that your project goes well!

The problem as described by Yvan definitely lends itself to an explicit code (PAMCRASH,ABAQUS/Explicit,LS-Dyna). I don't see many implicit codes, and certainly no version of NASTRAN, being particularly useful for dynamic collision with obstacles.
