Abstract

The three phase lag (TPL) thermoelasticity theory has been employed in this work to investigate wave propagation in a nonlocal porous medium. The governing wave-type equations are transformed into a homogeneous algebraic system, leading to non-trivial solutions that reveal the dispersion relation linked to propagation speed. From this dispersion relation, three coupled longitudinal waves (P waves, T waves, and V waves) and one transverse wave (SV-wave) are identified. The propagation speed is then plotted graphically. The effects of nonlocality, the heat flux relaxation time parameter and porosity are examined. In addition, the propagation speeds for the TPL and DPL models are examined. The influence of three phase lag (TPL) is investigated and presented via graphical representations. The already existed results in the literature are obtained by neglecting the porosity (void) parameter in the isotropic solid.

用三相滞后热弹性理论研究平面波在非局部多孔各向同性中的传播
本文采用三相滞后热弹性理论研究了非局部多孔介质中的波传播。将控制波型方程转化为齐次代数系统,得到非平凡解,揭示了与传播速度相关的色散关系。根据这种频散关系,可以识别出三个耦合纵波(P波、T波和V波)和一个横波(sv波)。然后用图形绘制传播速度。考察了非定域性、热通量松弛时间参数和孔隙率的影响。此外,还研究了TPL和DPL模型的传播速度。研究了三相滞后(TPL)的影响,并通过图形表示。文献中已有的结果都是忽略了各向同性固体的孔隙(空隙)参数而得到的。

期刊介绍: Archive of Applied Mechanics serves as a platform to communicate original research of scholarly value in all branches of theoretical and applied mechanics, i.e., in solid and fluid mechanics, dynamics and vibrations. It focuses on continuum mechanics in general, structural mechanics, biomechanics, micro- and nano-mechanics as well as hydrodynamics. In particular, the following topics are emphasised: thermodynamics of materials, material modeling, multi-physics, mechanical properties of materials, homogenisation, phase transitions, fracture and damage mechanics, vibration, wave propagation experimental mechanics as well as machine learning techniques in the context of applied mechanics.
