Hi there, I am doing research on slope stability analysis by Abaqus. I am following effective stress analysis. Can anybody suggest me some good resources where they analysed the slope with effective stress through abaqus. I will be very very appreciated of your help.

Hi there, I want to analyse a model in CEL where I want to analyse in two steps. After running the first step, I want to transform those results in next steps(Like all the stress components), then I want to analyse it from there. How to do this transformation in abaqus CEL?

Hi there, I run an analysis then extract the result in csv file and gave input as an initial condition in the next analysis. But I am facing some issues. The results should be like this photo: It is working fine for a model but when I use the different parts within same geometry then it...

But I am using Abaqus to simulate large scale deformation in CEL.

Sorry, I forgot to add the second figure. Here it is.

Hello There, I want to vary the Angle of Internal friction and cohesion with time. Here in the black arc at the bottom of the slope, I want reduce the strength parameters with simulation time. Say, at the very begining my angle of internal friction(Phi) is 28 and cohesion(c') is 10. It will...

Hi there, I was trying to model a cut soil to simulate the basal heave in narrow braced excavation. Here in this picture I used steel plate. After running the simulation the steel plate has moved down a little bit which is not acceptable. I used bottom point fixed in the steel plate. The soil...

Hello there, I am trying to model a slope. I have some initial von misses stress in ABAQUS. We know that the that Von misses yield strength is two times(2*Su) of undrained shear strength. So in my drained analysis, I need to fix the soil properties before failure so that the slope is stable in...

Is there any solution to go further? Can you please help me out?

I can use gravity loading. But if I want to use different earth pressure coefficient then how can I do it? Is there any other way to define it?

Hello Sir, Thank you so much for your prompt reply. Actually, my second step will be dynamic as I wrote the Modified Mohr-Coulomb VUSDFLD Subroutine for Dynamic analysis. I want to see that my slope is stable in the first step, and in my second step, I will apply the MMC where the slope might...

I tried that one too. It shows the same stress in both side. But I would expect different stress according to theory.

Hi, I want to model this slope in Geostress condition where I will expect this kind of result after end of the step. I can apply predefined field in the slope. I want to run this analysis in Dynamic Explicit Mode. But after running this analysis , I am not getting the expected result as this...

Excellent! I have a quick query to you. I am using Mohr Coulomb Hardening. I gave input angle of internal friction that is varying with PEEQ. And this PEEQ I used the following formula in this attached picture. So, My question is that does the ABAQUS calculate PEEQ based on Mohr Coulomb or thr...

Where the cohesion 'c' has gone? Is the determinant of strain tensor in last term? Also, Can you please share some reference? I really need this.

Hello Altruistic People, I believe everyone is fine. Let me explain something, I want to vary Angle of Internal friction and Cohesion with PEEQ. So I want to write VUSDFLD. Here, I don't understand that how to expand the PEEQ of Mohr-Cuolomb. I mean what could be the final solution of PEEQ in...

Thank you so much for your immense help. I will try to do.

Wow that's a nice idea. Unfortunately I don't know how to do it. Can you please give some suggestion how to do this things?

Though I tried to use smooth step and applied gravity load slowly. But my concern is that, in this process I am unable to apply lateral earth pressure coefficient which is available only in predefined field.

Yes it is for Dynamic Explicit. Is there anyway to get it stable?
