Project overview
The friction interfaces are a major source of nonlinearity and uncertainties in engineering structures caused by complex stick-slip motions, which may lead to nonlinear dynamical behaviour such as resonance frequency shift, amplitude dependent vibrations, modal interaction and friction induced vibrations. A wide range of evidence have shown that the failure of most engineering structure starts from or because of these friction interfaces due to fretting fatigue, wear or high cycle fatigue. The increasing use of lighter and more flexible structures makes the friction interface more important. Most of previous research on friction interface however were only focused on macro scale experiments and analysis, which generally fails to describe the contact mechanics in the friction interfaces and their micro/meso scale effects on the dynamical behaviours are poorly understood. The aim of this study is to develop advanced multi-scale framework to analyse and design the friction interfaces to make the dynamical systems more resilient and reliable.
