Unraveling the Secrets of Void Nucleation and Growth in α-β Titanium Alloys

/

Have you ever wondered how ductile metals like titanium alloys hold up under stress before ultimately failing? The answer lies in the process of void nucleation, growth, and coalescence. α-β titanium alloys are well-known for their exceptional properties such as strength, toughness, corrosion resistance, and resistance to fatigue failures. However, to fully utilize these properties, […]

Revolutionizing Wind Farm Efficiency: New Machine Learning Technique Predicts Optimal Layouts in Seconds

/

Researchers have developed a novel machine learning and pattern recognition approach to solving the wind farm layout optimization problem (WFLOP). The traditional row-by-row grids of turbines seen in many wind farms today can suffer from a 10-15% annual energy production loss due to inter-turbine turbulence called the wake effect. To minimize this loss, an optimal
