Special Issue Information

Dear Colleagues,

This Special Issue of Materials is devoted to original research and review papers on key topics related to the mechanical behavior of advanced composite materials and structures. Topics of interest include but are not limited to standard and non-standard experimental methodologies (tensile, compressive, bending, shear, impact, fatigue, crash testing, vibration, etc.), studies on anisotropy, fracture and damage (damage characterization and modeling), applications of numerical techniques for advanced modeling, multiscale modeling, and structural optimization methods for the lightweight design of advanced composite structures.

This Special Issue aims to provide an overview of the latest innovations related to advanced composite materials and structures. Contributions range from new theories and formulations to analyses and novel applications. Emphasis is placed on mechanics features of composite materials and structures. The issue focuses on experimental, numerical, and analytical studies on different aspects of advanced composite materials and their applications, with a specific focus on mechanical behavior.

In this paper, the energy absorption of Kevlar fiber and carbon fiber hybridized 3D woven composites under high-velocity impact loading was studied. A high-velocity impact model was established for the composites. The 3D Hashin and von Mises failure criteria were applied for the damage criteria of the yarn and matrix, and cohesive elements were inserted between them to simulate delamination. To validate the model, simulations were compared with test results. According to the results of the model, an algorithm based on artificial neural networks was also used to predict the hybridized composites for computational efficiency considerations. In the study of optimizing the energy absorption characteristics of three-dimensional woven structures, there is an optimal position and proportion of Kevlar hybridization to ensure the stiffness index of the structure. It is found that the position of Kevlar hybridization can result in considerable enhancement in the energy absorption of the target plate in the 3D woven structure. The proportion of Kevlar content affects the energy absorption of the optimal hybrid combination of the target plate. The energy absorption of the target plate can be effectively increased by adjusting the hybrid combination of different yarns under the condition that the Kevlar content proportion is constant, and the maximum energy absorption can be increased by 24.92%.

This study presents a spectro-geometric vibration model for analyzing free as well as forced vibration properties for FGM cylindrical double-walled shells with internal structures. The boundary conditions and coupling effects are modeled using an artificial virtual spring approach, which allows for the simulation of arbitrary boundary and coupling conditions by varying the elastic spring stiffness coefficients. The spectral geometry method is employed to represent the displacement variables of the FGM substructure, overcoming the discontinuity phenomenon commonly observed when traditional Fourier series are used. The dynamic equations of the FGM cylindrical double-walled shell with an internal structure are derived using the first-order shear deformation assumption and the Rayleigh–Ritz method, and the corresponding vibration solutions are computed. The model’s reliability and prediction accuracy are confirmed through convergence checks and numerical comparisons. Additionally, parametric studies are conducted to examine the influence of material constants, position parameters, and geometric parameters on the shell’s inherent characteristics and steady-state response.

This study introduces a novel analytical framework for investigating the vibration characteristics of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) elliptical cylindrical shells under arbitrary boundary conditions. Unlike previous studies that focused on simplified geometries or specific boundary conditions, this work combines the least-squares weighted residual method (LSWRM) with an adapted variational principle, addressing high-order vibration errors and ensuring continuity across structural segments. The material properties are modeled using an extended rule of mixtures, capturing the effects of carbon nanotube volume fractions and distribution types on structural dynamics. Additionally, virtual boundary techniques are employed to generalize elastic boundary conditions, enabling the analysis of complex boundary-constrained structures. Numerical validation against existing methods confirms the high accuracy of the proposed framework. Furthermore, the influence of geometric parameters, material characteristics, and boundary stiffness on vibration behavior is comprehensively explored, offering a robust and versatile tool for designing advanced FG-CNTRC structures. This innovative approach provides significant insights into the optimization of nanoscale reinforced composites, making it a valuable reference for engineers and researchers in aerospace, marine, and construction industries.
