o-ring "flexible"

[Login]

Good morning.
is it possible to model an o-ring in such a way as to make its size flexible and therefore simulate the deformation under load?

Thank you.

but you want to make a cinematic.. or a static image?

static image

models the oring.. and then do two facets one under and one on

if I design the o-ring with the profile via ellipse, then making the flexible component in the axieme, I can possibly deform it in a direction going to act on one of the two quotas.
If it is not something out of the world, there is a way to go to change a quota and make sure that I create it keeps me constant the area of the section and then go to calculate him how much to change the second length?

if it is not feasible, as explained it should shape the o-rings as an ellipse and go to make flexible the two dimensions, but sin that you go to the eye.

Maybe stupid question, but what level of detail and precision do you need? Is it just something aesthetic or is there more?

We both say.
I don't need a "micron" accuracy, but I wouldn't mind understanding through an axial compression, how much o-ring area would go on the wall radially.

a cad or software that simulates a similar condition, does not exist.
then visually you can imagine.
the idea of the ellipse could be good and not so discouraged by a circle with two facets
The facets, if we want to reproduce reality, you have to make them on the ellipse.

a "o-ring calculator" application can be downloaded on the trelleborg website. provides a lot of information about the o-ring crushing parameters to size the quarry according to operating pressure and material hardness. in practice the degree of filling of the quarry beyond the form it can take.

I took a look at the site calculator_o-ring herotrelleborg_homerecommends the size of the seats according to pressure and other interesting measures
but does not calculate the deformation of the o-ring as asked by @login

I took a look at the site site trelleborg site trelleborg 2interesting and there is a lot of information.
recommends the size of the seats according to the pressure.
but does not calculate deformation as asked by @login

It is true, but when you know that the quarry is ok, it matters little what the o-ring looks like, we say it fills it well, so your suggestion of the two flat faces remains valid. Moreover, depending on the side where the pressure is acting, the o-ring will stand on the opposite face as the trelleborg calculator suggests.

Okay, it doesn't matter what I look like

was not my problem.. but a problem @login
