Online Training: Selecting of soil models and parameter calibration in Midas GTS NX
■ Speaker Information
Dr. Sompote Youwai
Associate Professor, Geotechnical Engineering, Department of Civil Engineering at King Mongkut's University of Technology Thonburi (KMUTT)
■ Overview
The lecture will begin with the basic theory of the simple concept of the constitutive model for soil. He will present the simple mathematical formulation of the linear elastic model and the method to calibrate model parameters from laboratory and field tests. The next part is the basic formulation of the elastoplastic model. Dr. Sompote will summarize the concept in a simple way without complex mathematics.
The state-dependent models will be next summarized, which are soft soil model, hardening soil model, UBC sand model and Nor Sand Model. He also covers the model parameter calibration and optimization of their parameters in the lecture. Then, the application of the element test simulation called the “Soil Test” in Midas GTS NX will follow. It can simulate various tests such as triaxial in different stress paths and one-dimensional compression test in the drain and undrained conditions. Lastly, He will wrap up the presentation with a cases study of model calibrations.
