Regarding Boundary Conditions for Dynamic Soil-Structure Interaction Analysis

Hi all,

First, Congrats to the developers for this nice FEA suite.

I am practically a newbie in CAELinux. I could install CAELnux2008 and has just started using.

My area of interest is Dynamic Soil-structure interaction (DSSI). Therefore, I would like to know:
1. what are the non-linear material models implemented in CAE Linux suite?
2. what are the kinds of static/dynamic analyses (e.g. static push-over, transient, cyclic analysis) possible?
3. what are the boundary conditions (viz. reflecting, transmitting, absorbing, i.e. viscous dashpot-spring element) that are implemented in different softwares of the CAE suite?

Hope to get a reply so that before i invest time to learn these various interfaces, i may know if it is possible to do the DSSI analysis.

Thanks in advance

Hello Dr. Baishya,

I'm new here, and am also working with soil models. I've been trying to define a material for soil following simple Mohr-Coulamb.

If you have any idea as to how to do this, please reply. I was only able to see soil models following elastic behaviour, which is not helpful for me.

Hello d_riel,
in Code_Aster you can specify CJS Soil model which is similar to Mohr-Coulomb. See the reference manual for information how to transform the material parameters accordingly: www.code-aster.org/V2/doc/v10/fr/man_r/r7/r7.01.13.pdf (for version V10, corresponding V11 doc is currently down)

For an example of a triaxial test using CJS model you can have a look at the test cases SSNV135, SSNV136, SSNV154, SSNV155 or WTNV100.

Best regards,
Richard
