Practical Introduction to Non-Linear Finite Element Analysis (FEA)
2-day training course
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 non-linear finite element 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.
