Should the effective stresses be constant during the effective stress numerical analysis?

Assuming running the undrained effective stress analysis in FLAC3D via Config FLUID using the effective stiffness and strength parameters, are we expecting the constant effective stresses in the...

How can one remove the water level from the FLAC3D simulation at some point?

Is it possible to deactivate the effect of water so that FLAC adds the amount of steady state PWP to the effective stresses in all zones such that all the stresses in the soil constitutive model...

How are the horizontal stresses calculated in FLAC3D?

The very initial step of each project is setting up the in-situ stresses. Right after the said step as well as amidst the dynamic analysis, could you cast light on how FLAC internally does the...

How to assign the appropriate values to the interface element properties in FLAC3D?

Hey There. I am seeking a batch of references whereby the cohesion, friction angle, and dilatancy of the interface element, e.g., between a concrete foundation and the soil mass, could be...

In what condition is the assumption of the constant effective major stress applicable?

I was wondering what were the rationales behind making such an assumption in the soil mechanics and geotechnical earthquake engineering? Is it allowed to be used only in the static condition or it...

What is the appropriate distance between the side boundaries in a 3D numerical model of a soil-structure interaction system for a seismic analysis?

For instance, Rayhani and El Naggar (2008) posited that the said distance ought to be greater than five times of the superstructure width. Rayhani, M. H., & El Naggar, M. H. (2008). Numerical...
