Course content

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

Learning methods and activities

The course is taught in English and is made up by intensive lecturing in combination with exercises. The course is offered in the fall semester every second year (2024, 2026 etc.).

This course is part of NTNUs continuing education portfolio and has a tuition fee.

Compulsory assignments

  • Exercises

Further on evaluation

Home exam, 4 hours. Compulsory exercises must be passed before the exam. If there is a resit exam it might be an oral exam.

Required previous knowledge

MSc degree in geotechnical engineering or structural mechanics.

Course materials

Lecture notes in English will be available from Geotechnical Divison, NTNU.
