The course provides an introduction to non-linear finite element analysis. The treated sources of non-linearity are related to material properties (e.g. plasticity), kinematics (large deformations, instability problems) and boundary conditions (contact).
To be able to address all major sources of non-linearity in theory and numerics, and to apply this knowledge to the solution of relevant problems in solid mechanics.
1. Introduction: various sources of nonlinearities and implications for FEA. 2. Non-linear kinematics: large deformations, stability problems. 3. Non-linear material behavior: hyperelasticity, plasticity. 4. Non-linear boundary conditions: contact problems.
Lecture notes will be provided. However, students are encouraged to take their own notes.
Prerequisites / Notice
Mechanics 1, 2, Dynamics, Continuum Mechanics I and Introduction to FEA. Ideally also Continuum Mechanics II.
Performance assessment information (valid until the course unit is held again)
The performance assessment is offered every session. Repetition possible without re-enrolling for the course unit.
Mode of examination
written 90 minutes
Additional information on mode of examination
The written final exam (taking place during the examination session) covers all contents of this course, including lectures, exercises, and programming assignments. It counts 50% towards the final grade.
Additionally, there will be a compulsory continuous performance assessment in the form of a programming assignment that is broken down into five projects to be discussed and assigned during the course of the semester. Out of the five projects, at least four must be submitted two weeks after assignment. The best four submitted projects count 50% towards the final grade (12.5% each). These programming projects, which are integrated with the lectures and exercises, require the student to understand and apply the course material, and it involves programming in Matlab
One hand-written page of notes/formulae is allowed. No further material is allowed.
