Frances Fulton
Frances is a current PhD candidate, working with Vladislav Sorokin as her main supervisor. Her research interests are Nonlinear Dynamics, Acoustics and Structural Vibration. She is particularly interested in exploring the potential benefits of nonlinearity for vibration control applications using largely analytical methods. She completed her Masters in 2021 looking into incorporating nonlinear damping into a quasi-zero-stiffness vibration isolator and returned in 2022 to complete a PhD focused on the transmission of elastic waves through linear structures with an attached nonlinear absorber.
PhD Project
Frances’ current project is to analyse the vibration transmission behaviour of a rod with one or more attached Duffing type nonlinear absorbers. An analytical and numerical investigation into the vibration transmission and absorber displacement for one nonlinear absorber attached to a rod has been completed. An associated experimental analysis was completed in collaboration with Denmark Technical University. Following the analysis for a single absorber, transmission through a structure with multiple absorbers attached will be analysed. The goal of the research is to highlight the potential benefits of nonlinearity such as a wider frequency bandwidth of vibration suppression. This will allow for efficient metamaterial design.
