Practical Introduction to Non-linear Finite Element Analysis

Non-Linear Finite Element Analysis

Learn how to recognise when to use Non-linear FEA techniques, recognise the challenges that may be faced and identify the best approach to performing Non-linear analysis.

Finite Element Analysis is widely used in many industries to solve challenging structural analysis problems. With increasing computer power and advances in software, the scope and size of simulations far exceeds the capabilities of FEA even a few years ago.
However, frequently FEA training courses, whether Academic or Software Specific, do not teach FEA modelling skills and many users, (both new and fairly experienced), struggle in this area. With limited access to help, FEA users are not fully confident to achieve best practice and fail to achieve consistent reliable results.


NAFEMS addresses this requirement by providing this two-day course in Non-linear FEA in which attendees learn how to identify when non-linear analysis is required and the appropriate techniques to be applied.


Course Objective


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.


• 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?


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.

 

What’s Included.

The course fee includes morning and afternoon refreshments, lunch and a full colour copy of the lecture notes. Attendees are welcome to bring laptops to take notes, but they are not required (no software is used in the course). Attendees will receive a NAFEMS training certificate after completion of the course.
