adsorbing boundary and non linear analysis

[GiorgioAltin]

In a soil time-history analysis study we started from a linear 2D model and would like to move on to non-linear analysis by introducing the laboratory results obtained on the ground (damping and shear modulus curves). Can you suggest which material property model is more appropriate to use? Are there any sample models in 2d available?
Thank you

You may want to have a look at the OpenSees geotechnical examples as a general reference:

Materials such as PressureDepend(Independ)MultiYield(02/03) will allow you to use either built-in curves or your own backbone curves
