PARTNERSHIP:

Thesis between Chair of Applied Mechanics, TUM (DE) and University of Exeter (EN).

 

MOTIVATION:

Simulating the dynamic response of 3D high-fidelity FE model of structural components is very demanding in terms of computational cost. Reduced Order Modelling (ROM) techniques allow to dramatically reduce the cost of such simulations whilst maintaining the accuracy high. The main drawback of most of these techniques is the need for an intrusive implementation, meaning that they require ad-hoc FE softwares. Conversely, non-intrusive ROM can be obtained from any commercial software (e.g. Abaqus), making them more viable for industrial applications.

 

GOAL:

Implementation of a non-intrusive model order reduction technique in a finite element commercial software to enable fast and accurate simulation of structural vibration.

1. Literature study on nonlinear ROM 
2. Implementation of non-intrusive ROM in a commercial software (Abaqus)
3. Numerical experiments to test accuracy and convergence
4. Evaluation of results in comparison with other ROMs and full order simulations
