The course provides an introduction to non-linear finite element analysis. The treated sources of non-linearity are related to material properties (hyperelasticity, plasticity), kinematics (large deformations, instability problems) and boundary conditions (contact).
Lernziel
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.
Inhalt
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.
Skript
Lecture notes will be provided. However, students are encouraged to take their own notes.
Voraussetzungen / Besonderes
Mechanics 1, 2, Dynamics, Continuum Mechanics I and Introduction to FEA. Ideally also Continuum Mechanics II.
Leistungskontrolle
Information zur Leistungskontrolle (gültig bis die Lerneinheit neu gelesen wird)
Die Leistungskontrolle wird in jeder Session angeboten. Die Repetition ist ohne erneute Belegung der Lerneinheit möglich.
Prüfungsmodus
schriftlich 120 Minuten
Zusatzinformation zum Prüfungsmodus
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 involve programming in Matlab.
Hilfsmittel schriftlich
