Hi Anna, I have a problem which is close to your problem roughly. would you please let me know has your problem (stress concentration) been solved or not. If yes,I was wondering if you could help me. Thanks, Geotech2011

Hi, I was wondering if any body have any idea that how can I define the surface-to-surface interaction between the axisymmetric shell element(SAX1) and soil elemet(pore fluid/stress elemnt (CAX4P)). Regards, Geotech2011

Hi again, I read your explanation of your simulation once again, and I think you should change the type of your analysis step from static to soils. It might be solve your problem to get more acceptable results. Try it. Good luck :)

Hi, I'm sorry about that, but I haven't any other cae file which be close to your problem. By the way, what's your definition of soil/pile interaction? I think you should define contact interaction based on slide line formulation. Define surface to surface interaction and choose tangential...

Hi Anna, Please find the attached.http://files.engineering.com/getfile.aspx?folder=c0d47f40-dcda-4e54-8291-539ed0e3d538&file=long_term.inp

Hi Anna, Find the Attached(Inp file) which is analysis of pile driving. Hope, solve your problem.

I read your problem which you explain above, but I couldn't understand well that, what's your aim of this model. If it's possible, please let me know your purpose of this simulation. I'd like to help you and solve your problem. I have some experience in penetration pile .... in soil with Abaqus.

Hi Anna, has your problem been solved?

Hi, I am modelling an axisymetric model to simulate penetration a hallow cylinder into the soil. I defined sliding interaction between soil and cylinder in order to put the cylinder into the soil by sliding behavior. for this purpose, contact pairs surface were chosen ( Master & Slave ) so...

Hi, Check your Boundary conditions.

Hi, Thanks for your message. I define two steps: 1- Geostatic 2- soil . However the simulation says error message ( fix time increment is too large ). I was wondering if you could explain that how can I define many step varying the depth of penetration and how can I control the time of...

Unfortunately I do not have any experience regarding shell element. Good luck.

You can edit your soil set and add those plug elements which you want to assign stress initial condition for it.

I did not define two soil material properties, so I just define one stress initial condition.

Have you checked your plug element set? or re-define plug element set. may be it could be helpful. I modelled some models similar your model by axisymmetric and I did not have this problem.
