Practical Introduction to Non-Linear Finite Element Analysis
2-day training course
This non-linear Finite Element course is intended for delegates interested in using FE to analyse advanced non-linear problems involving material non-linearities, geometric non-linearities and contact problems.
The objectives of this Finite Element course are:
- To provide delegates with an introduction to the fundamental theory of non-linear FE analysis.
- To highlight the possible difficulties that may be encountered in using FE software to analyse non-linear problems.
Who Should Attend
This non-linear FE course is aimed at engineers and scientists who want to gain an understanding of the fundamental theory of non-linear Finite Element analysis and its application to practical problems.
As this is an advanced FE course, a pre-requisite for this course is a reasonable knowledge of linear FE theory and applications. However, no prior knowledge of non-linear Finite Element theory is required. The course is independent of any FE software code.
