Special Issue Information

Dear Colleagues,

This Special Issue focuses on the mechanical analysis of functionally graded graphene-reinforced composite materials and structures, highlighting their potential for advanced engineering applications. Functionally graded materials (FGMs) that incorporate graphene offer unique mechanical properties, such as high strength-to-weight ratios, improved stiffness, and enhanced thermal stability and structural performance. These characteristics make them ideal for applications in aerospace, automotive, and biomedical industries. This Special Issue welcomes research that explores theoretical, computational, and experimental studies on the design, analysis, and optimization of these advanced composites. Topics of interest include, but are not limited to, functionally graded graphene nanocomposites, graphene origami metamaterials, graphene smart materials, etc. Contributions are encouraged to emphasize the role of the material gradient in optimizing mechanical performance and to address challenges in manufacturing and practical implementation. This issue aims to serve as a comprehensive resource for researchers, engineers, and practitioners working on the development and application of these innovative materials and structures.

Forced vibrations resulting from moving loads, along with efficient vibration control, are essential in transportation engineering, earthquake engineering, and aerospace engineering. In this study, the vibrational response of an axially functionally graded (AFG) beam subjected to a moving harmonic load within a thermal environment was investigated. The primary aim was to explore the potential of controlling this vibration by incorporating a nonlinear energy sink (NES). A model for the AFG beam, with clamped–clamped boundary conditions, was developed using Euler–Bernoulli beam theory and the Lagrange method, accounting for the effects of the thermal environment and the moving load. The numerical simulations were performed using the Newmark method to solve the governing equations. The results demonstrated the effectiveness of the NES in mitigating the vibrational response of the beam under thermal and dynamic loading conditions. The effective reduction of maximum deflection caused by moving loads was set as the optimization objective to identify the most optimal parameters of the NES. The results were presented through a series of parameter analyses, revealing that the nonlinear damper can quickly dissipate the beam’s energy when the loads exit the structure. Furthermore, a properly designed NES can result in a 2.4-fold increase in suppression efficiency. Full article

This paper studies the thermomechanical low-velocity impact behaviors of geometrically imperfect nanoplatelet-reinforced composite (GRC) beams considering the von Kármán nonlinear geometric relationship. The graphene nanoplatelets (GPLs) are assumed to have a functionally graded (FG) distribution in the matrix beam along its thickness, following the X-pattern. The Halpin–Tsai model and the rule of mixture are employed to predict the effective Young modulus and other material properties. Dividing the impact process into two stages, the corresponding impact forces are calculated using the modified nonlinear Hertz contact law. The nonlinear governing equations are obtained by introducing the von Kármán nonlinear displacement–strain relationship into the first-order shear deformation theory and dispersed via the differential quadrature (DQ) method. Combining the governing equation of the impactor’s motion, they are further parametrically solved by the Newmark-β method associated with the Newton–Raphson iterative process. The influence of different types of geometrical imperfections on the nonlinear thermomechanical low-velocity impact behaviors of GRC beams with varying weight fractions of GPLs, subjected to different initial impact velocities, are studied in detail.
