Abstract

In this paper, we are following the plane time-harmonic waves propagation in an entire linear thermoelastic space, knowing the wavelength. Concerning the thermodynamic response, we fit the dual phase-lag model, while the effect of porosity on elasticity is given by Cowin–Nunziato theory. We obtain two shear waves and five longitudinal waves as: quasi-elastic wave, quasi-microrotational wave quasi-micropolar wave, quasi thermal mode, quasi-phase-lag thermal mode. The purpose of numerical simulations and of graphs is to identify the influence of connection between thermoelasticity, microrotation and porosity.

各向同性多孔微极性热弹性材料中具有两个延迟时间的波传播

摘要

在本文中，我们在已知波长的情况下跟踪平面时谐波在整个线性热弹性空间中的传播。关于热力学响应，我们拟合双相滞后模型，而孔隙率对弹性的影响则由 Cowin-Nunziato 理论给出。我们得到了两个横波和五个纵波：准弹性波、准微旋转波、准微极波、准热模态、准相位滞后热模态。数值模拟和图表的目的是确定热弹性、微旋转和孔隙率之间联系的影响。
