Abstract

By introducing a dependent variable and a special function satisfying the inhomogeneous mechanical boundary conditions, the governing equation for a new variable with homogeneous mechanical boundary conditions is derived. Then by means of the separation of variables technique and the electric and magnetic boundary conditions, the dynamic problem of a magneto-electro-elastic hollow sphere under spherically symmetric deformation is transformed to two Volterra integral equations of the second kind about two functions of time. Cubic Hermite polynomials are adopted to approximate the two undetermined functions at each time subinterval and the recursive formula is obtained to solve the integral equations successfully. The transient responses of displacements, stresses, electric and magnetic potentials are completely determined at the end. Numerical results are presented.

A generalized More-Gibson-Thomson heat transfer model for the study of thermomagnetic responses in a solid half-space
2023, Results in Physics
In this article, thermomagnetic interactions in a two-dimensional (2D), isotropic, homogeneous, and thermoelastic infinite half-space are discussed. It was proposed to use an improved version of the Moore-Gibson-Thompson (MGT) model of thermoelasticity. Since the relaxation time was taken into account in the Green-Naghdi formulation, this model was established. In addition, Maxwell's equations of magnetic and electric fields were taken into account during the formulation of the governing equations. The surface of the solid is considered to be free of traction, under the influence of a varying temperature, and immersed in a constant external magnetic field. In order to solve the non-dimensional coupled magnetic-thermal equations, the normal mode analysis approach and the deletion method were employed. The effects of the magnetic field, thermal factors, and other parameters on the investigated field variables are illustrated graphically and analyzed. There was also a comparison made between the outcomes of the suggested system and those of other thermal frameworks that can be derived as special cases. The results show that the MGT model reduced the magnitudes of the analyzed variables, which may have significant ramifications for various real-world scenarios.
Influence of imperfect interface and fiber distribution on the antiplane effective magneto-electro-elastic properties for fiber reinforced composites
2017, International Journal of Solids and Structures
The antiplane effective coefficients of two-phase piezoelectric–piezomagnetic periodic composite materials reinforced with cylindrical, unidirectional and periodically distributed fibers are computed by means of asymptotic homogenization method (AHM). The constituents have transversely isotropic properties belonging to 6 mm symmetry group and the periodic distribution of the fibers is assumed to be parallelogram-like as representative volume element (RVE). In the model, the imperfections are modeled as an idealization of spring–capacitor–inductor distributions at the interface. The antiplane local problems and the associated effective coefficients result of the AHM are explicitly described. The explicit formulae depend on the physical properties of the constituents of the phases and the constants that characterize the existence of the aforementioned imperfection. The validation of the present approach is shown by comparison with numerical results reported in the literature. The influences of the fiber spatial distributions and the imperfect fiber–matrix interface contact conditions on the effective properties are analyzed. Spatial fiber distribution induces some value changes in the magneto-electric coefficient and two possible composites property symmetry are obtained: monoclinic 2 and transversely isotropic. The effect of the imperfect contact parameter has a more pronounced value on the ME coefficient than the fiber distribution.

Thus from this results good convergence can be observed. Fig. 1 shows the time histories of hoop stress at inner surface for the elastic hollow sphere based on results of Wang and Ding [19] and the present methods. The figure illustrates a good agreement between presented analytically method (for 8 terms of Taylor's series in Eq. (37)) and Wang and Ding's [19] method.
In the present study, an analytical solution is presented to analysis dynamic behavior of FG (functionally graded) thick hollow sphere subjected to thermo-mechanical timed dependent loads. Thermo-elastic properties of FG, except for Poisson's ratio, are assumed to vary continuously and smoothly in the radial direction according to power law. Differential transform method (DTM) and Laplace transform method as efficient and accurate methods are used to solve the governing equations analytically for spatial domain and time domain respectively. Comprehensive parametric studies are carried out to show the influences of the power index, thickness and direction of FGM on the dynamic characteristics of the FG thick hollow sphere. The results in Laplace domain are transferred to time domain by employing the fast inverse Laplace transform (FLIT) method. Accuracy of present approach is assessed by comparing the numerical results with the results of published work in the literature.
Antiplane magneto-electro-elastic effective properties of three-phase fiber composites
2014, International Journal of Solids and Structures
In the present work, applying the asymptotic homogenization method (AHM), the derivation of the antiplane effective properties for three-phase magneto-electro-elastic fiber unidirectional reinforced composite with parallelogram cell symmetry is reported. Closed analytical expressions for the antiplane local problems on the periodic cell and the corresponding effective coefficients are provided. Matrix and inclusions materials belong to symmetry class 6mm. Numerical results are reported and compared with the eigenfunction expansion-variational method (EEVM) and other theoretical models. Good agreements are found for these comparisons. In addition, with the herein implemented solution, it is possible to reproduce the effective properties of the reduced cases such as piezoelectric or elastic composites obtaining good agreements with previous reports.

Examples of dynamic problems are as follows. Wang and Ding [10] analyzed the transient responses of a magneto-electro-elastic hollow sphere and a magneto-electro-elastic composite hollow sphere [11] subjected to spherically symmetric dynamic loads. Anandkumar et al. [12] analyzed the free vibration behavior of multiphase and layered magneto-electro-elastic beams.
This paper presents the theoretical analysis of a multilayered magneto-electro-thermoelastic hollow sphere under unsteady and uniform surface heating. We obtain the exact solution of the transient thermal stress problem of the multilayered magneto-electro-thermoelastic hollow sphere in the spherically symmetric state. As an illustration, we perform numerical calculations of a two-layered composite hollow sphere made of piezoelectric and magnetostrictive materials and investigate the numerical results for temperature change, displacement, stress, and electric and magnetic potential distributions in the transient state are shown in figures.

The static problems were analyzed in Refs. [5–8]. The dynamic problems were analyzed in Refs. [9,10]. With regard to functionally graded magneto-electro-elastic media, Ma and Lee analyzed an in-plane problem in functionally graded magneto-electro-elastic bimaterials [11].
This article is concerned with the theoretical analysis of the functionally graded magneto-electro-thermoelastic strip due to unsteady and nonuniform surface heating in the width direction. We analyze the transient thermal stress problem for a functionally graded strip constructed of the anisotropic and linear magneto-electro-thermoelastic materials using a laminated composite mode as one of theoretical approximation. The transient two-dimensional temperature is analyzed by the methods of Laplace and finite sine transformations. We obtain the solution for the simply supported and functionally graded magneto-electro-thermoelastic strip under a plane strain state. As an illustration, we carried out numerical calculations for a functionally graded strip composed of piezoelectric BaTiO₃ and magnetostrictive CoFe₂O₄, and examined the behaviors in the transient state for temperature change, stress, electric potential and magnetic potential distributions. Furthermore, the effects of the nonhomogeneity of material on the stresses, electric potential, and magnetic potential are investigated.
