Abstract
In this study, the circumferential interaction behaviour of the SH-wave with a piezoelectric cylinder coated with a viscoelastic material is investigated. The coating interface is imperfect and the viscoelastic material is subjected to pre-stress. By applying mathematical methods to the dynamical governing equations, expressions for displacement components and electric potential is obtained. Utilizing the set of boundary conditions, dispersion and damping equations are established for this model. The impacts of perfect & imperfect interfaces, piezoelectric & dielectric constants, initial stress, dissipation factor, attenuation coefficient and radial thickness ratio of materials on the phase and damped velocities of SH-wave are observed by numerical examples and graphical visuals.
本研究探讨了 SH 波与涂有粘弹性材料的压电圆柱体的周向相互作用行为。涂层界面不完美，粘弹性材料受到预应力作用。通过对动力学控制方程应用数学方法，得到了位移分量和电动势的表达式。利用边界条件集，建立了该模型的分散和阻尼方程。通过数值示例和图形直观地观察了完美和不完美界面、压电和介电常数、初始应力、耗散因子、衰减系数和材料径向厚度比对 SH 波相位和阻尼速度的影响。
期刊介绍：
Mechanics Research Communications publishes, as rapidly as possible, peer-reviewed manuscripts of high standards but restricted length. It aims to provide:
• a fast means of communication
• an exchange of ideas among workers in mechanics
• an effective method of bringing new results quickly to the public
• an informal vehicle for the discussion
• of ideas that may still be in the formative stages
The field of Mechanics will be understood to encompass the behavior of continua, fluids, solids, particles and their mixtures. Submissions must contain a strong, novel contribution to the field of mechanics, and ideally should be focused on current issues in the field involving theoretical, experimental and/or applied research, preferably within the broad expertise encompassed by the Board of Associate Editors. Deviations from these areas should be discussed in advance with the Editor-in-Chief.
