摘要

本研究的目的是研究具有两种温度的二维横向各向同性均匀磁热弹性介质中的记忆相关导数(MDD)。利用拉普拉斯变换和傅里叶变换技术解决了这个问题。为了在物理域中估计位移、应力和温度分布的性质,采用了一种有效的近似数值傅里叶反变换和拉普拉斯变换技术。本文用LS (Lord-Shulman)理论讨论了广义热弹性条件下均匀介质中位移、温度和应力的分布,并给出了解析形式。记忆相关导数的影响用图形表示。

Memory-dependent derivative approach on magneto-thermoelastic transversely isotropic medium with two temperatures

The aim of the present investigation is to examine the memory-dependent derivatives (MDD) in 2D transversely isotropic homogeneous magneto thermoelastic medium with two temperatures. The problem is solved using Laplace transforms and Fourier transform technique. In order to estimate the nature of the displacements, stresses and temperature distributions in the physical domain, an efficient approximate numerical inverse Fourier and Laplace transform technique is adopted. The distribution of displacements, temperature and stresses in the homogeneous medium in the context of generalized thermoelasticity using LS (Lord-Shulman) theory is discussed and obtained in analytical form. The effect of memory-dependent derivatives is represented graphically.
