Plane Strain Modeling

08/27/2012 5:22 AM

Hi All,
I am very new to FEM process and ANSYS as well.
I am trying to do a plane strain problem (2D) in ANSYS.
My problem is I don't know how to model primitives like sphere, cube, cylinder etc for 2D plane strain problem.
Like say can i model circle of 20mm radius for modeling sphere of 20mm radius???
Or can i model square of 50mm length for cube of 50mm.
May sound very dumb, but this is my genuine problem

Thank you for your time and help (in advance)

Hello,

I'm going out on a limb, because I don't use ANSYS, but another software platform and am also new to it. It seems that for a 2D interpretation, the software may regard your wireframe as axi-symmetric, meaning that to represent a sphere, you input a circle. Input a rectangle for a cylinder, etc.

Also, there are never any dumb questions, only dumb answers!

Good Luck!

Amitshah, I don't work with Ansys but I found this .pdf at

http://www1.ansys.com/customer/content/documentation/120/ans_mod.pdf.

Look at Chapter 5 and specifically section 5.3.1 which may be relavant to what your are trying to do. I didn't go through it so it's just a suggestion.

Btw, Amit, the term is 'planar'... Not trying to be picky here, but using the correct term will definitely aid your searches for information on the subject...
