Model Reduction of Mechanical Systems

Lecture Content

Nowadays, the use of lighter structures demands for the consideration of elastic effects for many components. Mostly, the modeling and numerical simulation of elastic bodies is achieved with the finite element method, which often leads to a high number of degrees of freedom, more than a million degrees of freedom is not unusual. Therefore, one essential step for an efficient simulation is the reduction of the elastic degrees of freedom. The complex model is replaced with a far simpler one, which still accurately captures the most important aspects of the phenomena being modeled.
This course presents the basic mathematical theory for projection-based model reduction. The lecture is accompanied by exercises, mainly practical Matlab programming exercises.

Information about the Lecture

  • Audience: 
    The lecture is intended for students in their MSc program as well as SimTech students.
  • Exercises: The lecture is accompanied by exercises, mainly practical Matlab programming exercises. It is allowed to work on them in groups of 2 to 3 students. Please upload only one solution per group to ILIAS.

Lecture

  • Wednesday, 8:00 a.m. to 9:30 a.m., V9.31

The lecture begins on Wednesday, October 20th, 2021.

Consultation Hours

The date of the examination consultation will be published in the future.

The lecture has a extent of 3 credit points, which corresponds to 2 semester hours per week (SWS).

A written exam is planned but depending on the number of participants it could be substituted in favor of an oral exam.
