本文用本征值方法研究了二维多孔材料在弱导、强导和正常导热条件下的力学行为。利用拉普拉斯-傅立叶变换和本征值技术，得到了变量的解析解。用简化的对称几何从多孔介质中获得的数值结果对所导出的技术进行了评估。计算结果包括位移、温度、应力和体积分数场的变化。比较了弱导电性、正常导电性和强导电性下的结果。
This work is devoted to the investigation of a two-dimensional porous material under weak, strong and normal conductivity, using the eigenvalues method. By using Laplace-Fourier transformations with the eigenvalues technique, the variables are analytically obtained. The derived technique is assessed with numerical results that are obtained from the porous mediums using simplified symmetric geometry. The results, including the displacements, temperature, stresses and the change in the volume fraction field, are offered graphically. Comparisons are made among the outcomes obtained under weak, normal and strong conductivity.
