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...
