## Properties

• Semester hours: 1.5
• Credits: 2.5
• Type: VO Lecture
• Format: Hybrid

## Learning outcomes

After successful completion of the course, students are able to...

• discuss the importance of soil mechanics related laboratory tests for nonlinear mathematical soil models,
• explain the laws of conservation relevant for soil mechanical modelling,
• describe the significance of plastic limit load analysis in soil mechanics,
• explicate the meaning of continuum mechanics for soil mechanical modelling,
• define the limitations of elasticity theory for soil mechanical issues,
• distinguish between mathematical soil models based on elastoplasticity and models based on the deformation rate and stress rate (e.g. hypoplasticity).

## Subject of course

The basic concepts of continuum mechanics and elasticity theory are reviewed. However, the course focusses on nonlinear mathematical models for soils like elastoplasticity, hypoplasticity and barodesy. The concepts of these constitutive models are discussed. In addition, the lecture includes an overview of the application of plastic limit load analysis, used in structural analysis and conservation laws in soil mechanical modelling.

## Teaching methods

Basics of continuum mechanics and elasticity theory for soil mechanical modelling are presented. Consequently, nonlinear constitutive models for soil and their differences are discussed. In addition, an overview of the application of plastic limit load analysis, used in structural analysis in soil mechanical modelling is given. Furthermore, the meaning of conservation laws for soil mechanical modelling will be explained. Simple numeric examples can be solved with the knowledge provided in this lecture.
