[Geoqus] Modeling footwall uplift in ABAQUS

[goteti rajesh]

Dear Users,


           I am trying to develop a simple model in ABAQUS: A 3D rectangular block has a single normal fault surface embedded in it which is defined as a frictional contact. When this block is stretched perpendicular to the fault strike, I can clearly see slip on the normal fault. But all of the slip is being accommodated by hanging wall subsidence as I do not have isostasy in my models. I would like to incorporate isostatic rebound into the model.

           Some of you may have incorporated isostasy (or a proxy of it) to simulate footwall uplift of a normal fault using ABAQUS. Could someone please advise me on the best way to go about doing this. Secondly, if you are aware of any ABAQUS CAE tutorial with geological examples, kindly let me know. 

Thanks in advance,
Rajesh

Subject: [Geoqus] ABAQUS and Soil Nailing Wall Modelling

Hi There,
 

 
I am new in this great ABAQUS forum. Actually I am doing a research on the impact of frost action on the soil nailing wall. I ran into some problems and really appreciate if you can help me out regarding that. I explain a bit more about that.
 

 
I deal with a 2D plain strain soil, plus concrete wall and steel nail which both is modeled beam element. Also As you now the model should be made based on staged construction. I have not problem in modelling stage construction, but my problem is mostly about interactions and thermal analysis.
 

 
To be more exact,  I do not what interaction I should define between soil / nail and soil / wall after each excavation, besides How can I apply temperature to my model?
 

 
I have made this model and if you need I can send you to examine.
 

 
Thank you in advance
 

 
Hamed
