how design a 2d solid with inner part as one material and outer as one

how design a 2d solid with inner part as one material and outer as one

how design a 2d solid with inner part as one material and outer as one

(OP)
hey all,
I want to know how u design a basic 2d plate with elasticplastic in the outer region and viscoplastic in the inner region.
i want to know how to sketch it.
The inner region is also a solid and its basically a 1/4 th of the outer region.
Thank u

Please write in English. Which program are you using?

RE: how design a 2d solid with inner part as one material and outer as one

you can design as one solid then "partition" solid into two volumes.

RE: how design a 2d solid with inner part as one material and outer as one

why not model two adjacent shapes (circles, i guess) ?

and assign different material properties to them

I think you should analyze the inner region, take the displacements from this and impose it upon the outer region in a separate model, superimpose the results in a third-party graphics...sorry, I can't keep going...WHAT are you talking about????

"A 2D Solid" is a misnomer...I assume you are referring to a plane stress or plane strain model.  If that is the case, I would think you are probably modeling two rectangles the outer of which has a height that is the thickness of your plate and a width that is the perpendicular dimension of your plate.  Then model the rectangle that would include the inner region of your plate.

Depending on what software you are using (see Greg's posting), you may need to duplicate your inner rectangle with properties of your outer rectangle (to close off the outer region).  Not sure what mesher you are using.  If an automatic mesher, you will need to do the duplicate rectangle that I mentioned.

Then follow rb's advice about assigning different material props.

After all this, I still have no idea if this even REMOTELY answers your question.
