Abstract

This study examines the propagation of shear waves on a highly inhomogeneous multi-layered elastic cylinder embedded in Winkler elastic foundations. The interface of the structure has been considered to bear generalized interfacial conditions, upon which the widely used perfect interfacial conditions turn out to be a special case. The harmonic wave solution has been deplored for the examination. Certainly, the discussion highlighted the roles of the Winkler foundation and layer thickness and the influence of material homogeneity versus non-homogeneity on the scaled phase velocity, dimensionless wave number, and scaled frequency, respectively, concerning layer thickness. In addition, it is observed that dimensionless vibrational displacements varied in response to changes in both the contact parameter \({{\varepsilon }_{a}}\) and the angle \(\theta \). Moreover, this study is set to supplement the known literature concerning the emerging field of multi-layered construction and provide insights into constructing reliable materials in the field of material science.

温克勒地基间非均匀多层弹性圆柱中的剪切波传播

本文研究了在温克勒弹性地基中嵌入的高度非均匀多层弹性柱体上剪切波的传播。本文认为结构的界面具有广义的界面条件，在此基础上，广泛使用的完美界面条件是一个特例。谐波解已被用于检验。当然，讨论强调了Winkler基础和层厚的作用，以及材料均匀性与非均匀性分别对层厚的标化相速度、无因次波数和标化频率的影响。此外，观察到无量纲振动位移随接触参数\({{\varepsilon }_{a}}\)和角度\(\theta \)的变化而变化。此外，本研究旨在补充有关多层结构新兴领域的已知文献，并为材料科学领域构建可靠材料提供见解。

期刊介绍： Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
