Abstract

Our current work is related to the study of vibrations induced by laser beams on the behalf of distinct theories of magneto-thermo-elastic diffusion problem in a semi-infinitely long, conducting isotropic elastic solid with cylindrical hole in a uniform magnetic field acting on the surface of the cylindrical hole of the solid in the direction of the axis of the cylindrical hole. The temporal scheme of laser beam is considered as non-Gaussian and is acted on the surface of the cylindrical hole. The problem is solved with the help of Laplace transform domain and finally illustrated graphically. Note: This article will be very useful in material science specially, in powder metallurgy during sintering, hot pressing, wire and rods annealing are examined from a unified physical point of view, in different branches of engineering physics like plasma physics, nuclear physics, geophysics and related topics and also in oil industry (Lyashenko and Hryhorova (2014), Long and Heng-Wei (2018), Fryxell and Aitken (1969), Nowinski (1978), Legros et al. (1998), Galliero et al. (2019) etc.).

不同广义热弹性理论下带圆柱孔的半无限弹性渗透固体在激光脉冲加热下的瞬态动力响应

我们目前的工作涉及研究激光束引起的振动，代表磁热弹性扩散问题的不同理论，在具有圆柱形孔的半无限长导电各向同性弹性固体中，在沿圆柱形孔轴线方向作用于固体圆柱形孔表面的均匀磁场中。激光束的时间格式被认为是非高斯的，并且作用在圆柱形孔的表面上。该问题在拉普拉斯变换域的帮助下得到了解决，最后用图形进行了说明。注：这篇文章在材料科学中非常有用，特别是在粉末冶金中，烧结、热压、线材退火都是从统一的物理角度进行研究的，在工程物理的不同分支，如等离子体物理、核物理、地球物理和相关主题，以及在石油工业中（Lyashenko和Hryhorova（2014），Long和Heng Wei（2018），Fryxell和Aitken（1969），Nowinski（1978），Legros等人。（1998），Galliero等人。（2019）等）。
