Special Issue Information

Dear Colleagues,

Composite materials have become the material of choice in high-end equipment fields such as aerospace, wind power generation, and modern construction due to their excellent lightweight characteristics, excellent specific strength, and highly designable properties. However, the vibration behavior of composite structures under dynamic loading presents significant anisotropic characteristics, complex damping mechanisms, and cross-scale coupling effects, which pose significant challenges to their dynamic performance, fatigue reliability, and noise suppression.

This Special Issue of Materials focuses on the vibration behavior of composite structures, aiming to bring together the most innovative theoretical breakthroughs, numerical simulation methods, and experimental characterization techniques in this field. The Special Issue focuses on the following research directions: (a) theoretical modeling and numerical simulation, such as analytical and numerical methods, multi-scale dynamics modeling, and nonlinear vibration analysis; (b) experimental characterization techniques, such as advanced testing methods, extreme environmental vibration test, damping performance evaluation; (c) vibration control and optimization, such as passive/active control technologies, smart material applications, and machine learning-assisted optimization. This Special Issue especially welcomes original research on advanced composite systems and their engineering applications.

Functionally graded porous beam (FGPB) structures are widely used in engineering due to their light weight, high strength, and vibration-damping performance. However, their energy localization and vibration suppression characteristics remain largely unexplored. To address this gap, this study proposes an axially functionally graded porous beam (AFGPB) structure capable of achieving energy localization and suppressing vibration transmission. A semi-analytical model is first developed within the Rayleigh–Ritz framework, using Gaussian functions as basis functions to accurately represent the displacement field. The accuracy of the model is validated by comparing its vibration characteristics with those obtained using the finite element method (FEM). Subsequently, the vibration behavior of double-AFGPB with simply supported boundary constraints is investigated. A series of numerical results are presented in this study to analyze the influence of porosity parameters on the energy localization effect and vibration suppression performance. Results reveal that the porosity power-law index N and truncation coefficient δ play key roles in energy localization and vibration suppression performance. When N ≥ 4, the energy localization effect and the vibration attenuation of the double-AFGPB become more pronounced with increasing N and decreasing δ, particularly in the low-frequency range.
