SemesterAutumn Semester 2022
LecturersL. De Lorenzis
Periodicityyearly recurring course
Language of instructionEnglish


AbstractThe 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).
ObjectiveTo 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.
Content1. 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 notesLecture notes will be provided. However, students are encouraged to take their own notes.
Prerequisites / NoticeMechanics 1, 2, Dynamics, Continuum Mechanics I and Introduction to FEA. Ideally also Continuum Mechanics II.
