Wall-Soil interaction problem with contact2D and PressureDependMultiYield material

Dear STKO

I am trying to improve the pseudo-static wall-soil model I posted before with PressureDependMultiYield02 material in order to capture the accumulation of earth pressure during every two constant wall displacements. I have some problems with the model.

After applying 5 cyclic ...

Re: Contact2D problem with a wall-soil interaction model

Dear STKO

According to your suggestion last time, I made some changes to the model. Now, the wall's movement seems reasonable; however, the soil mass deformation and the earth pressure development behind the wall are still problematic/unrealistic.

First, let me specify again the object we want to ...

Re: Contact2D problem with a wall-soil interaction model

Dear Prabakaran

Thanks for your response!

I am simulating a wall in contact with the backfill soil that is 0.96m high and 1m wide in the 2D plane. The cyclic point displacement is applied on the wall at the height of 0.87m. I use the units kilonewton for the self-weight of the backfill and ...

Contact2D problem with a wall-soil interaction model

Dear STKO

I am trying to replicate a pseudo-static wall-soil experiment with cyclic displacement and trying to get the earth pressures behind the wall using Contact2D material and BeamContact2D element.

I am simulating the first step so that a small strain condition should be on using elastic ...
