Dear all,
I am new to Abaqus, and would ask you two questions in Abaqus modeling, related to soil materials. For example a model is used to simulate the pile static testing, a two soil layer model is created by partitioning one part into two partitions in Abaqus version 6.14-2:
Firstly, the interface between the two partition will be an interface for the two soil formations, will this interface need to apply contact interaction or constraint?
Secondly, after I have applied the initial geostatic stress (gravity stress) and got initial equilibrium. there are two more standard steps in this model, loading step and unloading step. In CREATE STEP popup window, should I choose 'Static, General', or 'Geostatic'? Because I heard that all static steps in soil related model should use the 'Geostatic' step, not a 'Static, General' step.
Thank you very much,
David
1) if soil layers have an ideal mechanical contact on the interface, then it is better to use a single body dшvided into two cells with different material properties; however, if slippage or delamination is taken into account, then use two separate layers and specify interaction on the interface.
2) geostatic can be substituted by static general
Dear Sergey, thank you so much for your pertinent answers, They are very helpful. best regards, David
