A free-surface-only closure model for linear waves on general deep-water flows
Emanuele Zuccoli, Edward James Brambley, Dwight Barkley
We present a novel, spatially two-dimensional (2D) set of equations to study the propagation of linear deep-water surface waves over a general steady three-dimensional (3D) backgro…
The Weakly-Nonlinear Admittance at Open Ends of Two- and Three-Dimensional Acoustic Waveguides
Freddie Jensen, Harry Turnbull, Edward James Brambley
We formulate a weakly-nonlinear exit condition for open ends of acoustic waveguides; to our knowledge this is the first time a general acoustic open end has been analysed outside t…
Modelling Lateral Spread in Wire Flat Rolling
Mozhdeh Erfanian, Carl D. Slater, Edward James Brambley
A mathematical model for wire rolling is developed, focusing on predicting the lateral spread. This provides, for the first time, an analytic model of lateral spread without any fi…
Multimodal nonlinear acoustics in two- and three-dimensional curved ducts
Freddie Jensen, Edward James Brambley
We develop a weakly nonlinear model of duct acoustics in two and three dimensions (without flow). The work extends the previous work of McTavish & Brambley (2019, J. Fluid Mech. 87…
Careful finite element simulations of cold rolling with accurate through-thickness resolution and prediction of residual stress
Francis Flanagan, Alison N. O'Connor, Mozhdeh Erfanian +3
Metal rolling is a widespread and well-studied process, and many finite-element (FE) rolling simulations can be found in the scientific literature. However, these FE simulations ar…
Through-Thickness Modelling of Metal Rolling using Multiple-Scale Asymptotics
Mozhdeh Erfanian, Edward James Brambley, Francis Flanagan +2
A new semi-analytic model of the metal rolling process is introduced, which, for the first time, is able to predict the through-thickness stress and strain oscillations present in…
