Special Issue Information

Dear Colleagues,

The fields of aerospace and mechanical engineering are at the forefront of technological advancement, propelled by the unrelenting evolution and implementation of sophisticated materials and technologies. The advantages of these innovations are numerous and are critical in improving the performance, reliability, and efficiency of aerospace systems and mechanical components.

Advanced composites, including carbon fiber reinforcements and ceramic matrix composites, are extensively utilized in the aerospace and mechanical engineering domains due to their exceptional mechanical attributes, lightweight nature, and durability. Nanocomposites present novel avenues for enhancing the functionality of components by modifying material properties at the microscopic scale. The development of multifunctional materials can not only enhance the mechanical strength and durability of components but also endow them with new functions, including self-healing, self-cleaning, and environmental sensing.

Moreover, novel methodologies in advanced technologies pertaining to structural vibration and noise control, such as active vibration control and intelligent damping systems, have demonstrably enhanced dynamic performance and ride comfort in aerospace vehicles and mechanical systems. The incorporation of these technologies not only enhances the ride experience but also improves the safety and longevity of the system.

Our Special Issue on "Advanced Materials and Technologies for Aerospace and Mechanical Engineering" aims to explore the latest developments in materials science and engineering technologies to drive innovation in these fields. We invite researchers and practitioners to contribute original and high-quality papers, and the scope of the call for papers includes, but is not limited to, the following areas:

  • Lightweight materials for structural applications;
  • Piezoelectric and magnetostrictive materials for smart actuators and sensors;
  • Data analytics and machine learning for predictive maintenance;
  • Thermal management in high-power aerospace systems;
  • Simulation and modeling of noise and vibration phenomena in complex systems.

Cor-Ten steels, also known as weathering steels, are construction materials of growing importance in the field of architecture and crash barriers, not only due to their good mechanical and corrosion resistance properties but also for the appealing color of their oxides. However, a complete description of the fracture locus of Cor-Ten steels in both low and high triaxiality ranges is still lacking. The present study aims at integrating and extending the data available in the literature for this peculiar material by evaluating four different planar specimens with a mixed numerical–experimental methodology. A non-notched specimen was tested in terms of tension to calibrate the true stress–strain curve of the material after necking by means of an iterative process involving the FEM. Once the model had been calibrated, a tensile test of each specimen was simulated, and the corresponding results were validated using the experimental test data. From the FEM results, the quantities of interests, namely, the stress triaxiality, the equivalent plastic strain, and the normalized Lode angle, were extrapolated. Subsequently, the fracture locus of the Cor-Ten steel was determined through the interpolation of the experimental data collected in the present study as well as data available in the literature for low triaxiality ranges. The results confirmed the parabolic trend characterizing the fracture locus at low triaxiality suggested in the literature, and an exponential decreasing trend was found at higher triaxiality values after reaching a local maximum. The results thus confirm that the fracture locus of Cor-Ten steels, as generally found for metallic materials, cannot be completely described by a monotonic function. Moreover, it was found that the highly ductile behavior of the material induces a significant topology change in the specimens before failure, thus making it more complex to forecast the location of crack nucleation and, as a consequence, the stress state.

In this study, we determined an aerodynamic configuration to design structures applying composites for large-scale horizontal-axis wind turbine blades. A new aerodynamic and structural design method for large wind turbine blades is presented. The rated power of the wind turbine blade is 25 MW class. The tip speed ratio is 7. The diameter of the designed blade is 260 m. Therefore, thick airfoils were selected to design large-scale wind turbine blades considering structural stiffness and maximum lift coefficients. For the aerodynamic design method, it was designed with the optimal angle of attack having the maximum lift-to-drag ratio. The blade element theory and vortex theory were applied to aerodynamic design. For the aerodynamic design results, its validity was investigated via aerodynamic performance analysis. As a result of analyzing aerodynamic performance, it was confirmed that higher power was generated. At 12.5 m/s of rated wind speed, electrical power was 28.32 MW. The structural design considering the aerodynamic design results was carried out. The composite laminate theory was adopted. Structural safety was evaluated for the designed blades. Finally, the structural design results were analyzed as sufficiently valid. Full article

In order to achieve the goal of a lightweight shaft–disk rotor, this paper applies the fiber woven composite material to the disk structure, and at the same time considers the design of the weight-reducing holes on the porous disk. It introduces the domain decomposition and coordinate mapping technology for this, and then establishes the dynamics model of the fiber woven composite material shaft–disk rotor. The model is based on the differential quadrature finite element method, which is suitable for fiber woven composite rotors with arbitrary complex hole patterns. The validity of the model is verified by comparing the results with the literature, finite element simulation, and experiments, and the mechanism of the influence of the material parameters and pore parameters on the vibration characteristics of the system is investigated, which provides the data support and theoretical basis for the analysis of the dynamics of the fiber woven composite rotor.
