摘要

建立了一个由两种不同各向同性热弹性均质材料组成的实心圆柱体热弹性模型。讨论了热流和应力张量的边界条件。应用双相滞后模型来研究其热物理性质。为了对其进行数值评估，考虑了具有界面热接触电阻和整体弹性波电阻的双层结构以及一些特殊情况。这项研究将有助于建立纳米尺度的热弹性理论模型，以及设计纳米和多层器件、板材和表面涂层。

Dual-Phase Lag Model for a Solid Cylinder Made of Two Different Thermoelastic Materials

A thermoelastic model for a solid cylinder consisting of two different isotropic thermoelastic homogeneous materials is created. Boundary conditions for the heat flow and stress tensors were discussed. A dual-phase lag model was applied to investigate its thermophysical properties. For their numerical evaluation, a two-layered structure with an interfacial thermal contact resistance and an integral elastic wave resistance, as well as some special cases, were considered. This study will be useful for theoretical modeling the thermoelasticity at the nanoscale and for designing nano and multilayered devices, plates, and surface coatings.
