Comparison between experimental results and numerical simulations for a vibratory friction rig.]]> 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.

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.
