# Short Courses (CPD)

### Soil Modelling and Numerical Methods

• Monday 30 January - Friday 3 February 2017

This course provides you with an introduction to the basic features of commonly used constitutive models capable of describing soil behaviour, and an understanding of the principles of numerical modelling.

You'll be introduced to the advantages and limitations of different models of soil behaviour, and provided with an understanding of how to select the appropriate soil parameters. Presentations and specially prepared notes and tutorial exercises are combined with the use of geotechnical finite element software to provide a thorough knowledge and understanding of soil modelling.

The course will:

• introduce you to a range of constitutive models capable of describing soil behaviour;
• provide you with an understanding of the principles of numerical modelling;
• enable you to develop a working knowledge of geotechnical finite element programs.

#### Who is the course aimed at?

The course offers an introduction to soil modelling and numerical methods in geotechnical engineering along with the use of the commercial finite element package Plaxis. The course is designed for complete beginners in Geotechnics along with practitioners with previous experience who wish to update their knowledge.

## Objectives and Outline

### Soil Modelling and Numerical Methods

#### Course Objectives

By the time you've finished the course, you'll be able to:

• describe the basic features of commonly used models of soil behaviour
• understand the advantages and limitations of different models of soil behaviour, and select the appropriate soil parameters
• use a finite element program to analyse a wide range of geotechnical problems such as foundation or embankment loading situations.

Elastic models: characteristics of soil behaviour, strain increments and stress variables, elasticity, drained triaxial test, undrained triaxial test, measurement of elastic parameters - oedometer, in-situ geophysics, plate loading, pressuremeter, anisotropy, nonlinearity-secant and tangent stiffness, advantages and limitations of elastic models.
3. Elastic-plastic models: yield surface - Tresca criterion, Von-Mises criterion, Mohr-Coulomb criterion, hardening models, plastic flow rules.
4. Elastic-perfectly plastic Mohr-Coulomb model: elastic properties, yield criterion, flow rule, elastic-plastic stiffness matrix, selection of soil parameters.
5. Extended Mohr-Coulomb model.
