which software for impact/destructive simulation?

Submitted by phsieh2005 on

Hi,

I am evaluating a couple of software packages for impact and destructive testing simulation.

What are the strength and weakness of the following packages in terms of explicit solver capability for impact/destructive?

NX Nastran non-linear (with explicit solver)

NEi Nastran explicit

ANSYS explicit solver (new in ANSYS 12)

 

Thanks!

Hi phsieh,

I can suggest you a software, recently used by a collegue who interests in crash testing study---> "Visual crasch studio"

n.b.: I think is only a graphic solver, but i will give you more and detailed informations about it, if you need..

Dear phsieh,

I know that, probably, you have to deepen this argument with a focus on internet or blog, but I have some informations:

- Impact design, europe version 2003 - 2010   (probably, there is the company, you should investigate about it!)

- it's a software in collaboration with HONDA+  (...)

Also, I'll post you the contact of a polish professor, who interests about it, in his theorical studies; I give you his references:

Hi,

 Lsdyna is so poweful to model crash and impact. it gives you flexibilty to write your own UMA and it is explicit.

Thanks Azadeh!

 I did use LS-Dyna for a couple of years in the past.  I am just not good enough in understanding how the code works.  I had to strugle with diverged runs quite often.  So, I am looking for something not as powerful, but, more robust.  I do not really need very accurate results, just for trending and gross weak areas of the design.
