## Practical Introduction to Non-Linear FEA

### 2-day training course on 1st & 2nd October

This non-linear Finite Element course is intended for delegates interested in learning how finite elements are used to analyse advanced non-linear problems, difficulties encountered in modelling real-life applications and guidelines for using non-linear finite element technology.

The objectives of this Finite Element course are:

• To provide delegates with an introduction to the fundamental theory of non-linear Finite Element analysis.
• To highlight the possible difficulties that may be encountered in using finite element software to analyse non-linear problems.

## Who Should Attend?

This course is aimed at engineers and scientists who want to gain an understanding of the fundamental theory of non-linear finite element analysis, solution accuracy, difficulties and application to practical problems.

As this is an advanced finite element course, a pre-requisite for this course is a reasonable knowledge of linear finite element theory and applications. However, no prior knowledge of non-linear finite element theory is required. The course is independent of any finite element software code.
