Presentations and Plenary videos to 9th edition of the International Conference on Computational Methods for Coupled Problems in Science and Engineering (COUPLED PROBLEMS 2021)

The objectives of COUPLED PROBLEMS 2021 are to present and discuss state of the art, mathematical models, numerical methods and computational techniques for solving coupling problems of multidisciplinary character in science and engineering. The conference goal is to make step forward in the formulation and solution of real life problems with a multidisciplinary vision, accounting for all the complex couplings involved in the physical description of the problem.

The conference is one of the Thematic Conferences of the European Community on Computational ... show more

CT23 - Multi-Physics Problems

Effect of fretting-wear on dynamic analysis. Comparison between experimental results and numerical simulations for a vibratory friction rig.
F. Tubita, A. Fantetti, L. Blanc, F. Thouverez

9th edition of the International Conference on Computational Methods for Coupled Problems in Science and Engineering (COUPLED PROBLEMS 2021).

Abstract
Dry friction in contact interfaces can have an important impact on the dynamic response of jointed structures subjected to vibration. It may cause frettingwear leading to a modification of the contact surface geometry by producing wear debris through material removal and dissipating energy. Consequently, the contact behaviour is modified and the worn geometry induces a change in vibrations level. Therefore, it is important to be able to simulate these complex phenomena occurring at the interfaces to predict the forced response of assembled structures and also their life-expectancy to design high confidence components. A multi-scale approach is implemented considering a slow-scale for wear phenomena and a fast-scale for the non-linear dynamic response and applied to validate an experimental test.

PIEZOELECTRIC BEAM FINITE ELEMENT MODEL AND ITS REDUCTION TO STATE-SPACE MODEL
V. Kutis, J. Paulech, G. Galik, J. Murin, V. Goga

9th edition of the International Conference on Computational Methods for Coupled Problems in Science and Engineering (COUPLED PROBLEMS 2021).

Abstract
The paper deals with modeling and simulation of the connection of piezoelectric materials, FGM materials and LQR control, using state-space model, which is built by modal truncation MOR method. FEM equations of piezoelectric finite beam were implemented in FEM program MultiFEM written in Wolfram Language. Modal truncation MOR method, which uses results from modal analysis, is also implemented in program Wolfram Mathematica. Simple piezoelectric structure is analyzed in numerical experiments, where FEM results are compared with MOR results.
