One‐Dimensional Finite Elements With Arbitrary Cross‐Sectional Displacement Fields
International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.ABSTRACT This paper introduces an unprecedented unified approach for developing structural theories with an arbitrary kinematic variable over the beam cross‐section. Each of the three displacement variables can be analyzed using an independent expansion function. Both the order of the expansion and the number of terms in each field can be any. That is,

Dynamic Stall Characteristics of Thick Wind Turbine Airfoils
Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT This paper studies the dynamic stall characteristics of thick flatback and nonflatback wind turbine airfoils. Two airfoils with a maximum thickness of 35%$$ 35\% $$ were studied, with trailing edge thicknesses of 2%$$ 2\% $$ and 10%$$ 10\% $$, respectively.

Main rotor-body action for virtual blades model
EPJ Web of Conferences, 2018 This research aims to investigate a virtual blade model and assess rotor influence on helicopter fuselage aerodynamics. The rotor disk is discretized in the azimuthal direction, and a time-varied pressure jump is applied in regions occupied by the blades.

The Effect of Rotor Size on the Teeter Behavior of Two‐Bladed Wind Turbines
Wind Energy, Volume 28, Issue 11, November 2025.ABSTRACT The rotor of a two‐bladed turbine allows the implementation of an additional degree of freedom around the rotating hub y‐axis. This idea is over 60 years old, and various research and commercial turbines have had a teeter hinge. Fatigue and extreme loads can be reduced significantly with a teeter hinge. Teetered turbines have been mainly below

Polymer Composites, Volume 46, Issue S1, Page S9-S25, 10 September 2025.Typical manufacturing defects and mitigation strategies in thick thermosetting composites. Abstract The composite part industry is currently dominated by thin‐section geometries. However, thick composites gain interest in many applications where monolithic parts are required, such as foils, wind mill root blades, and so forth.
