Course content

The course is given every second year, next time fall semester 2022. Finite element based computer codes for geotechnical analysis are today frequently used in design by consulting engineers. This course provides a background for development and application of soil models in such computer tools. This is done by focusing on soil behavior, elasto-plastic theory, hyperplasticity using thermodynamics, some material models and their parameters. In addition the course aims at providing a theoretical framework for understanding the mechanical behavior of soils. A short summary of relevant continuum mechanics is given in the first lectures followed by a detailed presentation of simple models based on Tresca and Coulomb. The main principles are discussed with emphasis on shear hardening in combination with dilatancy control. Further a model based on "Critical State Soil Mechanics" with volumetric hardening will be covered. The models will be evaluated partly by using a thermodynamic approach and compared to observed soil behavior from laboratory tests. An introduction to more advanced models is given together with a discussion of current research topics. Algorithms for implementation in computer codes are covered.

Learning outcome

Knowledge: The candidate should have knowledge of: - how elasto-plastic stress-strain relations for soils are formulated and how these relations may describe the strength and stiffness of soils Skills: The candidate is able to: - develop simple numerical models for soil behavior - modify existing numerical soil models - assess input parameters for characterising relevant elasto-plastic soil behaviour - test the characteristic behaviour of the model General competence: The candidate can: - understand the soil behaviour in the theory frame of elasto-plasticity - describe field and laboratory tests through elasto-plastic numerical soil models - implement soil models in a finite element program
