With the significant increase in the application of composite materials in engineering, it has become an important topic in the engineering field to study the impact behavior and damage mechanism of these materials under different impact conditions. This paper reviews the commonly used high and low-speed impact test methods for composite structures in recent years. It briefly introduces the design principles, advantages, disadvantages, and applicable scope of each method. Finally, it summarizes the discussed high and low-speed impact test methods for composite structures and provides some suggestions for future development, aiming to offer useful references for the advancement of impact test methods for composite structures.
Fluid-structure interaction is widely present in various engineering problems in the aviation field and has been the focus of numerical simulation analysis. Considering the fluid-structure interaction in numerical simulation research is of great significance for structural safety. In this paper, the characteristics of the meshed and meshless fluid-structure interaction algorithms are introduced systematically by modeling methods, and the new trends of fluid-structure interaction algorithms such as the immersed boundary method and machine learning are reviewed. Some applications of fluid-structure interaction algorithms in the aviation field are introduced. Finally, some suggestions for the development of fluid-structure interaction algorithms and their applications in the aviation field are concluded.
With the significant increase in the use of composite materials in engineering applications, the damage problem of composite materials under low-velocity impact loading has received extensive attention. This paper sorts out the more commonly used low-velocity impact analysis methods for composites in recent years, and briefly introduces the design principles, advantages and disadvantages, and the scope of application of each method, and finally summarizes the introduced low-velocity impact analysis methods for composites and some suggestions for future development, expecting to provide useful references for the subsequent development of low-velocity impact analysis methods for composites.
