Abstract

The purpose of this research is to examine the effects of magnetic field and thermal diffusion on a photo-thermoelastic semiconducting medium under the theory of hyperbolic two-temperature. During the formulation of the problem using the hyperbolic two-temperature theory, the relation between plasma and thermoelastic waves was explored. The medium is assumed to be a semiconducting medium with isotropic and homogeneous characteristics. The Laplace transform technique is used to construct analytic formulations for physical quantities such as stresses, displacement components, temperature field, and mass concentration. To show the results, numerical computations are done using the MATHEMATICA program for the selected material (Si). To demonstrate the significance and effectiveness of the obtained results, the full solutions of the major physical variables in the space-time domain are found using a numerical method based on the inverse of the Laplace transform. A comparison is carried out with and without a magnetic field, at different theories (CTE, LS, GL) and with another research that agree with the previous paper when the new parameters neglected.

双曲双温光热波下具有扩散性的磁致热弹性半导体介质
本研究的目的是在双曲双温理论下研究磁场和热扩散对光热弹性半导体介质的影响。在利用双曲双温理论提出问题的过程中,探讨了等离子体和热弹性波之间的关系。假设介质为具有各向同性和均匀特性的半导体介质。拉普拉斯变换技术用于构建应力、位移分量、温度场和质量浓度等物理量的解析公式。为了显示结果,使用 MATHEMATICA 程序对所选材料(硅)进行了数值计算。为了证明所获结果的重要性和有效性,使用基于拉普拉斯变换逆的数值方法找到了主要物理变量在时空中的全解。比较了有磁场和无磁场、不同理论(CTE、LS、GL)以及另一项研究,当新参数被忽略时,这些结果与前一篇论文一致。

期刊介绍: Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
