Journal Article
Clot, A., Meggitt, J., Langley, R., Elliott, A., & Moorhouse, A. (2021). An experimental exploration of the properties of random frequency response functions. Journal of Sound and Vibration, 491, 115773. https://doi.org/10.1016/j.jsv.2020.115773

The vibro-acoustic analysis of complex structures over a broadband frequency range is an extremely challenging problem that may often require the use of a hybrid deterministic-statistical approach. Due to manufacturing imperfections, the frequency re... Read More about An experimental exploration of the properties of random frequency response functions.

Finite element model updating using in-situ experimental data (2020)
Journal Article
Meggitt, J., & Moorhouse, A. (2020). Finite element model updating using in-situ experimental data. Journal of Sound and Vibration, 489, 115675. https://doi.org/10.1016/j.jsv.2020.115675

Conventional model updating methods are based on frequency response functions (FRFs) and/or modal parameters estimates obtained from freely suspended, or sometimes rigidly constrained, sub-structures. These idealised boundary conditions are however... Read More about Finite element model updating using in-situ experimental data.

A framework for the propagation of uncertainty in Transfer Path Analysis (2020)
Journal Article
Meggitt, J., Moorhouse, A., Weinen, K., & Sturm, M. (2020). A framework for the propagation of uncertainty in Transfer Path Analysis. Journal of Sound and Vibration, 483, 115425. https://doi.org/10.1016/j.jsv.2020.115425

Transfer Path Analysis (TPA) is a test-based methodology used to analyse the propagation of noise and vibration in complex systems. In this paper we present a covariance based framework for the propagation of experimental uncertainty in classical,...
