“…Under such conditions, the wave velocity values are given by equations (22), (23) and (24). Adopting the parameter as listed above in our numerical computation, we have tried to analyse the trends of the behavior of plane wave propagating in the medium under different media conditions and load conditions with respect to two G-N models.…”

“…The field of study known as magneto thermoelasticity has applications in several areas, particularly in nuclear devices, biomedical engineering and geomagnetic investigations. Some of the works related to this field are Abd-Alla and Al-Dawy [1,2], Ezzat and Othman [10], Ezzat [9], Ezzat et al [11], Wang et al [25], Othman and Song [22], Othman [19], Othman and Said [23]. A number of discussions relating wave propagation in rotating isotropic or anisotropic media were reported in literature, some of which are the works of RoyChoudhuri [7], Gupta and Gupta [14], Singh [24], Maity et al [16,17].…”

The article is concerned with the possibility of plane wave propagation in a rotating elastic medium under the action of magnetic and thermal fields. The material is assumed to be fibre-reinforced with increased stiffness, strength and load bearing capacity. Green and Nagdhi's concepts of generalized thermoelastic models II and III have been followed in the governing equations expressed in tensor notation. The effects of various parameters of the applied fields on the plane wave velocity have been shown graphically.

“…A new theory of generalized thermoelasticity has been constructed on the basis of the two-temperature generalized thermoelasticity theory for an anisotropic and homogeneous body without energy dissipation by Youssef (2011). Othman et al (2015) studied the effect of magnetic field on generalized thermoelastic rotating medium with two temperatures under five theories. This new theorem has been constructed in the context of Green and Naghdi type II model of linear thermoelasticity.…”

Purpose The purpose of this paper is to investigate the dynamic response for a thermoelastic infinite medium with a spherical cavity in the context of the theory of two-temperature thermoelasticity without energy dissipation. Design/methodology/approach The cavity is fixed and subjected to a subjected to harmonically varying temperature. Findings The exact expressions for displacement, temperature and thermal stresses are computed and represented graphically. These distributions are calculated for a copper material and results are analyzed. Originality/value Effects of non-simple heat conduction, frequency of thermal vibrations and magnetic field are depicted graphically on the field variables.

Purpose The purpose of this paper is to study a model of the equations of a two-dimensional problem in a half space, whose surface in a free micropolar thermoelastic medium possesses cubic symmetry as a result of inclined load. The problem is formulated in the context of Green-Naghdi theory of type II (G-N II) (without energy dissipation) and of type III (G-N III) (with energy dissipation) under the effect of magnetic field. Design/methodology/approach The normal mode analysis is used to obtain the exact expressions of the physical quantities. Findings The numerical results are given and presented graphically when the inclined load and magnetic field are applied. Comparisons are made with the results predicted by G-N theory of both types II and III in the presence and absence of the magnetic field and for different values of the angle of inclination. Originality/value In the present work, the authors study the influence of inclined load and magnetic field in a micropolar thermoelastic medium in the context of the G-N theory of both types II and III. Numerical results for the field quantities are obtained and represented graphically.
