Cut in two piece

Level 9

Cut in two piece

Hello

I do a test simply with a washer, see the sketch enclosed.

I do the simulation with the whole puck and then with half of the puck as well as half of the load.

And I get not the same result to Von Mises:

Entire puck 750.0 [MPa]

Puck half 642.0 [MPa]

When you cut a piece in half to do more than the symmetrical connection.

Kind regards.

Re: Cut in two piece

Hi Denis,

Where are your stresses measured?

Do the contact forces balance/add up?

How is your F1 & F2 applied?

Re: Cut in two piece

Good morning Charles.

In reality the force F1 is the support reaction of the force F2.

I have an F1 support that is done on a dia crown. Ext of 42.0 [mm] and dia int of 30.0 [mm].

The force F2 of 30 [KN] acts on a ring of dia ext of 30.0 [mm] and dia int of 23.0 [mm]

Thickness of washer 3.25 [mm]

Cordially.

Re: Cut in two piece

Hello Paul,

Thanks for this very interesting answer in its design, I take

good note.

I am attaching a picture of the representation of the puck split in half with the

a half load whose constraints are not identical.

As stated in the first post.

I may be forgetting to do something when you cut a piece by

its plane of symmetry.

Kind regards.

Hello Denis,

OK, maybe 2d contact better?

Re: Cut in two piece

Hello

Thank you for your new shipment.

I'm going to watch it.

But what I still don't understand, is why when I simulates half a piece by the plane of symmetry, I do not get the same results.

Kind regards.

Re: Cut in two piece

Hello Denis,

your model is wrong, half too,

not constraints possible, contact only.
