Abstract

Abstract This work demonstrates deformation in hygrothermoelastic medium with an overlying non-viscous fluid of uniform thickness. A constant mechanical force is applied along the fluid-layer. The normal-mode analysis technique is applied to solve the governing equations of the medium. The analytical expressions of displacement, moisture concentration, temperature distribution, and stresses are obtained for the hygrothermoelastic medium and depicted graphically for different values of fluid-layer depth. The finding of this work is that the values of the aforementioned physical quantities decrease with an increase in the fluid-layer, which justifies the decaying nature of waves with depth. The novelty of the problem is that no research has been carried out so far for analyzing hygrothermoelastic medium subjected to thermoelastic deformation.

上覆非粘性流体的湿热弹性介质中力学源的理论研究

摘要本文研究了湿热弹性介质上覆均匀厚度非粘性流体的变形问题。沿着流体层施加恒定的机械力。采用正模分析技术求解介质的控制方程。得到了湿热弹性介质的位移、水分浓度、温度分布和应力的解析表达式，并以图形形式描述了不同的流体层深度值。这项工作的发现是，上述物理量的值随着流体层的增加而减小，这证明了波随深度衰减的性质。该问题的新颖之处在于，迄今为止还没有对热弹性介质进行热弹性变形分析的研究。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation.
