nD Concrete Material

Post by trin »

Dear Developers,
I am trying to model a concrete wall which behaviour is controlled by flexural and shear deformations. I was therefore wondering whether there is a concrete material which I could use in conjunction with brick elements? Or could you recommend any other way of modelling the problem?
Thanks a lot for your help,
Trin

Hello Trin,

You can try using Template 3D EP, there we have Leon Parabolic model that is used for concrete...
You can allways use Drucker-Prage or mohr-Coulomb as well...

What is the aspect ratio of the wall in question? Also what is the type of wall you are working with, rect, T, C, etc. I am working on T-walls and am using fiber beam-column elements, it is fast to solve, and for a rectangular wall I modeled gave me very good results. The wall had a aspect ratio of 3:1. T-walls don't waor as good but I am trying to fix that now. Hope that helps..

shear deformation with fiber elements

Post by Boris »

how do you take into account the shear deformation in walls (which is the predominant mode of deformation) using fiber elements (1D, Bernoulli beam, plane cross section theory behind it...)?
