Hi PLAXIS community,
I would like to ask you about the soil-soil interface, please. If I want to choose the formula for elastic sliding, which is determined by the elastic shear stiffness of the interface and the function of the interface thickness. What value of Ks should be taken and how exactly is the interface thickness defined. Is it related to the meshing at the interface, is it determined numerically or is it related to a physical quantity? I would appreciate if you could explain the issue to me. I am willing to validate a hyperbolic law to describe the interface at the soil-soil level, so I am using Plaxis to calculate the initial stiffness of the curve.
Thank you in advance.
