Using ANSYS For forging...
Aravind Melligeri
Has anybody used ANSYS for simulation of the forging [hot or cold] process?.
If so any pointers on how to go about it [ type of elements, loading method
etc...]
Thanks

Dont! Unless you have release 5.0 of ANSYS, don't even try.
The earlier release of the program don't include large strain effects,
except for the hyperelastic elements.

This is true. Not to plug any particular vendor or anything, but while we routinely
use ANSYS for most types of modelling, for our superplastic forming work (quite
similar to forging in some ways) we use a code called MARC. It's available from:
MARC Analysis Company 415-329-6800 FAX: 415-323-5892
With ANSYS up to 4.4a, all kinds of problems occur when you get strains over
10-20% (depending on element type).

1. food-safe
2. fairly machinable
3. resistant to moisture effects
4. resistant to high temperature (~100 C)
Does anyone know where I can find such information? The material
selection catalogs I've looked at aren't very detailed. Delrin
(DuPont acetal) was recommended as a possibility, but I have no hard
info about the suitability of Delrin for food container use.
Thanx for any help,

We got ABAQUS instead because ANSYS just couldn't hack it.

What about SDRC IDEAS latest version [ I believe 6.0] ?. I heard they have
included the non-linear elements in it. Anyone modelled using these elements.

I agree! MARC may be more suitable than ANSYS. Another commercial code
DEFORM may have the most powerful feature, automatic remeshing. We used
DEFORM for simulating forging of titanium disk up to 80% reduction in
height. Unlike ANSYS and MARC, DEFORM is based on rigid viscoplastic
formulation.
DEFORM is marketed by Scientific Forming Technology Corp. (614-268-8385),

ANSYS too has many nonlinear capabilities, and has had them for a long
time. These include geometric nonlinearities, such as large deflections,
and material nonlinearities, such as plasticity, swelling, and creep
for its structural elements. My statement was that earlier releases
of ANSYS did not include >>> large strain effects <<< for the
usual structural elements. With the exception of the hyperelastics,
the formulation of the structural elements simply did not take
large strains into account. But this is not the same as saying
that ANSYS has had no nonlinear capability. I've used most
of the above mentioned nonlinear capabilities of the program,
with little difficulty, so long as the total strain did not
exceed 10% by much.
But, other programs beware. Release 5.0 of ANSYS, now being distributed,
has had all its popular structural elements reformulated to
include large strain effects too.

Besides MARC, another code used for large strain analysis is ABAQUS.
This is a commercial general purpose (but non-pc) FEM product.
Call 401-727-4200 for more info.

They sell alot of lab equipment which is made from "food-safe" plastic.
If you get a copy of their catalog, I think you'll be able to find what
you need.
