Abstract

This paper introduces curvilinear fiber laminated plates into the design of phononic crystal structures, proposing a model of periodic curvilinear fiber laminated plates and establishing a framework for band gap analysis. Specifically, we compare the band gap calculation results obtained using the finite element method (FEM) with those obtained using the plane wave expansion method, verifying the accuracy of our numerical approach. Based on this, we compare the band gap characteristics of curvilinear fibers and straight fibers, finding that the inclusion of curvilinear fibers significantly enhances the low-frequency band gap performance of the structure. Furthermore, we analyze the influence of the curvilinear fiber orientation parameters, discovering that these parameters affect the band gap characteristics of the structure. By adjusting the curvilinear fiber orientation parameters, it is possible to tailor the band gap properties to meet specific engineering requirements, greatly enhancing the design flexibility of the structure. Finally, we investigate the propagation of waves in various directions within the periodic curvilinear fiber laminated plates. Studies indicate that wave propagation in curvilinear fiber laminated plates exhibits more complex phenomena compared to straight fiber laminated plates. The patterns of wave energy flow also validate the effectiveness of the band gap.

期刊介绍： Mechanics of Materials is a forum for original scientific research on the flow, fracture, and general constitutive behavior of geophysical, geotechnical and technological materials, with balanced coverage of advanced technological and natural materials, with balanced coverage of theoretical, experimental, and field investigations. Of special concern are macroscopic predictions based on microscopic models, identification of microscopic structures from limited overall macroscopic data, experimental and field results that lead to fundamental understanding of the behavior of materials, and coordinated experimental and analytical investigations that culminate in theories with predictive quality.
