Effects of Hold Time on the Elevated Temperature Fatigue Crack Growth Behavior of Alloy 247LC‐DS
Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT Creep–fatigue crack growth (CFCG) experiments were performed at 850°C and 950°C on nominally 12.70‐mm‐thick compact‐type specimens of alloy 247LC‐DS, a Ni‐base superalloy. The loading cycles consisted of trapezoidal waveforms with hold times of 2 and 20 min at the maximum force.

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.ABSTRACT In this study, the influence of resin cross‐link density on thermomechanical properties and fatigue behavior of polyurethane resins and glass fiber‐reinforced polyurethane (PUR‐GFRP) composites was investigated. This material is a candidate for renewable energy applications like rotor blades in wind turbines.

Journal of Product Innovation Management, EarlyView.ABSTRACT Academic Summary Despite the urgent need for a circular economy, firms' transition from linear to circular business models (CBMs) remains slow. While previous research suggests that dynamic capabilities are the key drivers of this transition, it assumes a direct link, overlooking that these capabilities can facilitate change but do not ...

Export controls and the energy transition: Aligning security and sustainability
Review of European, Comparative &International Environmental Law, EarlyView.Abstract This article examines how the accelerating use of export controls, once motivated by narrow security interests, can now affect the pace and success of the global energy transition. As strategic rivalry intensifies among the US, the EU and China, export controls increasingly target access to critical and emerging technologies such as advanced ...

Wind turbine blades vibration: review
Multidiszciplináris TudományokThe rapid development of wind turbines and the elongation of their blades necessitate extensive studies to address higher loads, displacement and vibrational amplitude, nonlinearity in the geometry, nonlinear stiffness, and many other challenges. Moreover, as many countries are shifting towards wind energy due to its effectiveness and low environmental

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Weibull‐Neural Network Framework for Wind Turbine Lifetime Monitoring and Disturbance Identification
Wind Energy, Volume 29, Issue 4, April 2026.ABSTRACT Wind turbines are vital for sustainable energy, yet their reliability under diverse operational and environmental conditions remains a challenge, often leading to costly failures. This study presents a novel Weibull‐Neural Network Framework to enhance wind turbine lifetime monitoring by estimating reliability (R(t)) and mean residual life (MRL)
