Steering topology distributions for unified generative design of architected metamaterials
Haolin Li, Yuyang Miao, Menglei Li +9
Architected metamaterials derive their functions from structure, creating vast opportunities to program physical responses through topology design. However, existing design methods…
Homotopy continuation of viscoelastic waveguide dispersion curves: from intra-manifold tracking to inter-manifold transport
Dong Xiao, Zahra Sharif Khodaei, M. H. Aliabadi
Conventional mode tracking operates in the dark: it traces dispersion branches on the non-Hermitian eigenvalue manifold using only local continuity, unaware of the global Riemann-s…
Discrete Solution Operator Learning for Geometry-Dependent PDEs
Jinshuai Bai, Haolin Li, Zahra Sharif Khodaei +3
Neural operator learning accelerates PDE solution by approximating operators as mappings between continuous function spaces. Yet in many engineering settings, varying geometry indu…
Wind-turbine wake effects on the rate of accumulation of fatigue damage in overhead conductors
Francisco J. G. de Oliveira, Kevin Gouder, Zahra Sharif Khodaei +1
Guidance relating to the safe distance within which overhead conductors (OHCs) should not be built with respect to a wind turbine, and vice versa, varies from country to country. I…
The effect of tip-speed ratio and free-stream turbulence on the coupled wind turbine blade/wake dynamics
Francisco J. G. de Oliveira, Martin Bourhis, Zahra Sharif Khodaei +1
Wind turbines operating within wind farms experience complex aerodynamic loading arising from the interplay between wake-induced velocity deficits, enhanced turbulence, and varying…
Physics-guided impact localisation and force estimation in composite plates with uncertainty quantification
Dong Xiao, Zahra Sharif-Khodaei, M. H. Aliabadi
Physics-guided approaches offer a promising path toward accurate and generalisable impact identification in composite structures, especially when experimental data are sparse. This…
