This paper is concerned with the study of reflection of longitudinal displacement waves from the flat boundary of an elastic half-space containing a distribution of void pores. The half space is under the action of a uniform magnetic field and the magnetic field is applied in such a direction that the problem can be considered as a two dimensional one. The critical value of the frequency has been detected. Amplitude ratios have been presented. The effects of magnetic field on various subjects of interest are discussed and shown graphically. © 2013 Elsevier Ltd. All rights reserved.

This work is concerned with the propagation of time harmonic plane waves in an infinite nonlocal thermoelastic solid having void pores. Three sets of coupled dilatational waves and an independent transverse wave may travel with distinct speeds in the medium. All these waves are found to be dispersive in nature, but the coupled dilatational waves are attenuating, while transverse wave is nonattenuating. Coupled dilatational waves are found to be influenced by the presence of voids, thermal field and elastic nonlocal parameter. While the transverse wave is found to be influenced by the nonlocal parameter, but independent of void and thermal parameters. For a particular model, the effects of frequency, void parameters, thermal parameter and nonlocality have been studied numerically on the phase speeds, attenuation coefficients and specific losses of all the propagating waves. All the computed results obtained have been depicted graphically and explained. © 2019, © 2019 Taylor & Francis Group, LLC.

Plane waves in nonlocal thermoelastic solid with voids

In this paper, plane wave propagation in a rotating anisotropic material of general nature under the action of a magnetic field of constant magnitude has been investigated. The material is supposed to be porous in nature and contains voids. Following the concept of [Cowin S. C. and Nunziato, J. W. [1983] "Linear elastic materials with voids," J. Elasticity 13, 125-147.] the governing equations of motion have been written in tensor notation taking account of rotation, magnetic field effect and presence of voids in the medium and the possibility of plane wave propagation has been examined. A number of particular cases have been derived from our general results to match with previously obtained results in this area. Effects of various parameters on the velocity of wave propagation have been presented graphically. © 2016 World Scientific Publishing Europe Ltd.
