Course content

The course is given every second year, next time fall 2010. 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, 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 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.

Learning outcome

This course focuses primarily on the development and use of constitutive models in computational geotechnics. In addition the purpose is improved understanding of the behaviour of soil as an engineering material. The course provides useful principles for interpretation of laboratory tests.

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 fall every second year (2010 - 2012). Normally top international guest lecturers give part of the course.
