I am studying the behavior of kaolin clay under cyclic loading. The strain rate is kept at such that undrained behavior is maintained. I want to use an advanced constitutive model to predict this behavior, but would first need to calibrate it. I understand that calibration means that I have to input such model parameters with which the model can reasonably predict the testing results. I am using the excellent testing resource on kaolin clay by Dr. Wichtmann (Wichtmann, 2018). I would like to ultimately calibrate the advanced constitutive model using the Soil test feature on Plaxis. But I have no idea how to calibrate a model and it would really help me if you can provide me with some guidance or guide me to resources that can help me to do this. I think starting with a simpler constitutive model will be better (modified cam clay perhaps).
Thank you for reading this post! Your valuable input is much appreciated!
Kind regards
