Choose your soil model wisely if you want your calculations to stand up


The mechanical behaviors of soil can vary dramatically, and the success and accuracy of a numerical model will often rest on the choice soil model to begin with.

In this two-part webinar, we first examine the families of constitutive models available within PLAXIS’s model library, the material behaviors you might expect from them, and how the choice of the right soil model can be critical within finite element modelling predictions. As an example, we look at a deep excavation with a retaining wall and compare predictions using different soil models. 

In the second part, we swap from using soil constitutive models to describe behavior qualitatively, and move on to using soil constitutive model parameters to quantify specific aspects of that behavior, such as stiffness and strength. This includes a walk-through of how that calibration process works within PLAXIS, plus an examination of the SoilTest option, a quick and convenient procedure to simulate basic soil lab tests on the basis of a single point algorithm.
