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:
This non-linear Finite Element Analysis 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.

● Creep and Visco-elasticity
Basic theory of creep, niaxial and multiaxial creep therory, time and strain hardening, Explicit and implicit time integrations, Discussion of typical practical creep applications.
● Contact Problems
Basic theory of contact mechanics, classification of contact configurations, Hertzian and non-Hertzian contact problems, Finite Element contact algorithms, Penalty methods and Lagrange multipliers, Difficulties in modelling contact problems, Tips and guidelines, Discussion of practical contact problems.
