The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Aeroelastic analysis of a troposkien-type wind turbine blade [PDF]
The linear aeroelastic equations for one curved blade of a vertical axis wind turbine in state vector form are presented. The method is based on a simple integrating matrix scheme together with the transfer matrix idea.

ABSTRACT Fatigue is the most common reliability failure mechanism and has been studied widely since the 19th century. Material specimens are used in laboratory experiments to obtain fatigue test data. An S‐N curve is used to depict the relationship between the stress (or strain) S$$ S $$ and the number of cycles to failure N$$ N $$. Statistical methods

From the reviews, a new concept of a low‐speed centrifugal pump (LSCP) driven by a vertical ultra‐low‐head hydro turbine (VULHT) was designed and tested on simulation and physical setup. It was performed with a 1.8 m delivery head, concluding as inefficient. For ultra‐low‐head conditions, different than centrifugal action is recommended.

Vertical Axis Wind Turbine with Inverter
Increased demand for renewable energy has led to efficient wind energy conversion systems. This project focuses on the design and implementation of vertical axis wind turbines (VAWTs) with inverters to efficiently produce and use clean energy. In contrast to traditional wind turbines on horizontal axis, VAWTS can grasp the wind from all directions and ...

Guy cable design and damping for vertical axis wind turbines [PDF]
Guy cables are frequently used to support vertical axis wind turbines since guying the turbine reduces some of the structural requirements on the tower. The guys must be designed to provide both the required strength and the required stiffness at the top

To address high‐altitude power transmission challenges, a composite controller was developed to suppress strong wind interference, demonstrating the effectiveness of hierarchical control in complex dynamic systems. Hardware‐in‐the‐loop experiments verified the robustness of the control algorithm, providing methodological support for developing ...
