Topic: Plane stress / Plain strain

How can I choose between the 2 states? Where in the program is situated this option?

I saw here (http://www.cervenka.cz/consulting-proje … sed-design) "A tunnel section of 1 m length was modelled in ATENA 2D in plane strain state" and I'm trying to do the same.

Thank you

Re: Plane stress / Plain strain

Dear francisco, the Plane Strain Idealization can be activated by checking the box of the same name on the "Basic" tab of the material dialog for "3D Nonilinear Cementitious 2" (NLCem2). For elastic materials, choose the corresponding material type "Plane Stress Elastic Isotropic" or "Plane Strain Elastic Isotropic".

Please understand the SBETA material only supports Plane Stress, and that mixing Plane Strain and Plane Stress in a single model is not supported by ATENA Engineering 2D.
