Abstract

In the present work, the transmission characteristics of piezoelectric/piezomagnetic phononic composite laminates with and without a defect layer are predicted using the plane wave expansion and the stiffness matrix methods. The energy transmission and reflection spectrums show the appearance of two band gaps. The effect of the variation of the thickness of the epoxy layer on the transmission characteristics is also discussed. In addition, a passband can be produced and controlled within the band gap when inserting a defect layer. The effect of magnetoelectric constants, piezoelectric e₁₅ constant with piezoelectric defect layer (BaTiO₃) as well as q₁₅ piezomagnetic constant with piezomagnetic defect layer (CoFe₂O₄) on transmission coefficient is further studied. These findings could be relevant to understanding the intrinsic physical properties of phononic piezoelectric-piezomagnetic composite laminate and provide flexible choices to meet real engineering applications.

压电/压磁声子复合材料层板传输性能研究

本文采用平面波展开法和刚度矩阵法对有无缺陷层的压电/压磁声子复合材料层板的透射特性进行了预测。透射光谱和反射光谱显示出两个带隙。讨论了环氧层厚度的变化对传输特性的影响。此外，当插入缺陷层时，可以产生通带并将其控制在带隙内。进一步研究了磁电常数、带有压电缺陷层(BaTiO3)的压电e15常数以及带有压电缺陷层(CoFe2O4)的q15压磁常数对透射系数的影响。这些发现有助于理解声子压电-压电复合材料层合板的内在物理特性，并为实际工程应用提供灵活的选择。

期刊介绍： Archive of Applied Mechanics serves as a platform to communicate original research of scholarly value in all branches of theoretical and applied mechanics, i.e., in solid and fluid mechanics, dynamics and vibrations. It focuses on continuum mechanics in general, structural mechanics, biomechanics, micro- and nano-mechanics as well as hydrodynamics. In particular, the following topics are emphasised: thermodynamics of materials, material modeling, multi-physics, mechanical properties of materials, homogenisation, phase transitions, fracture and damage mechanics, vibration, wave propagation experimental mechanics as well as machine learning techniques in the context of applied mechanics.
