Aircraft are multidisciplinary systems that are challenging to design due to interactions between the subsystems. The relevant disciplines, such as aerodynamic, thermal, and propulsion systems, must be considered simultaneously using a path-dependent

Wind turbines are complex multidisciplinary systems that are challenging to design because of the tightly coupled interactions between different subsystems. Computational modeling attempts to resolve these couplings so we can efficiently explore new

While most physics involved in wind energy are nonlinear, linearization of the underlying nonlinear wind system equations is often important for understanding the system response and exploiting well-established methods and tools for analyzing linear

Zhang, Z, Zhang, L, Jasa, J, Negahban, M & Gazonas, G 2022, ' Molecular sources of ratcheting in poly-dispersed polycarbonate ', International Journal of Fatigue, vol. 154, 106567 . https://doi.org/10.1016/j.ijfatigue.2021.106567
Molecular dynamics (MD) of polycarbonate is used to understand the molecular bases of ratcheting and sensitivity to variation in polymer chain lengths. We find that ratcheting is almost insensitive to molecular weight in mono-disperse systems, but no

Urban air taxis, also known as urban air mobility (UAM) vehicles, are anticipated to be an area of significant market growth in the near future. These vehicles are typically vertical take-off and landing (VTOL) designs which are capable of carrying 1
