摘要

本文研究了磁场和初始应力作用下的孔隙热弹性问题。我们应用正态分析来求解得到的无量纲耦合方程。给出了位移、温度分布、孔隙压力、应力、感应电场和感应磁场分布的数值结果，并进行了讨论。介质由于热冲击和磁场作用而发生变形，在介质中产生感应磁场和感应电场。通过二维和三维的数值分析，说明了孔隙度参数、磁场和初始应力参数对物理变量的影响。

Electromagnetic field and initial stress on a porothermoelastic medium

In this study, the porothermoelastic problem with the effect of the magnetic field and initial stress was investigated. We applied normal mode analysis to solve the resulting non-dimensional coupled equations. Numerical results for the displacements, temperature distribution, pore pressure, stresses, induced electric field and induced magnetic field distributions are presented graphically and discussed. The medium deformed because of thermal shock and due to the application of the magnetic field, there result an induced magnetic and an induced electric field in the medium. Numerical analyses are given graphically on the square (2D) and cubic (3D) domains to illustrate the effects of the porosity parameter, magnetic field and initial stress parameter on the physical variables.
