Uncertainty Quantification of Aeroelastic Stability
, 2014 The application of uncertainty analysis for the prediction of aeroelastic stability, using probabilistic and non-probabilistic methodologies, is considered in this chapter. Initially, a background to aeroelasticity and possible instabilities, in particular “flutter,” that can occur in aircraft is given along with the consideration of why Uncertainty ...

Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section
Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations
Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT Low‐level jets (LLJs) describe conditions in which the wind speed reaches a local maximum with respect to altitude near the surface; they have been observed intermittently in the US mid‐Atlantic offshore environment. LLJs pose unique operating conditions for future wind turbines operating in the region, such as negative shear and locally ...

Propagation of structural uncertainty to linear aeroelastic stability
Computers & Structures, 2010 The problem of linear flutter analysis in the presence of structural uncertainty is addressed. Whereas the propagation of uncertain structural parameters in finite element models has been carried out by a number of different methods, there appears to be less published work on the influence of random structural parameters on flutter speed. In this paper,

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis
International Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...

Experimental Seismic Response Assessment of Tall Buildings With Large Mass Damping
Earthquake Engineering &Structural Dynamics, Volume 54, Issue 15, Page 3707-3725, December 2025.ABSTRACT This paper describes an experimental investigation into the seismic performance of a novel integrated damping system. The proposed damping concept mobilises a portion of the building's own mass to generate damping from its differential motion relative to the lateral load‐resisting system.
