Some Backward in Time Results for Thermoelastic Dipolar Structures
Frontiers in Physics, 2020 In our study, we define the linear backward in time problem for a thermoelastic body with a dipolar structure. In our first main result, we prove the uniqueness of the solution for this problem.

Advanced Engineering Materials, Volume 27, Issue 10, May 2025.A novel technique for fabricating monolithic functionally graded NiTi shape memory alloy (SMA) laminated hybrid composite has been developed. An excellent metallurgical bonding can be established between two compositionally different NiTi SMAs through spark plasma sintering joining/diffusion bonding followed by hot roll bonding.

Effect of magnetic field on piezo-thermoelastic medium with three theories
Results in Physics, 2017 In the present paper, we use the classical dynamical coupled theory, Lord-Shulman theory with one relaxation time, and Green-Lindsay with two relaxation times of thermoelasticity to study the influence of magnetic field on piezo-thermoelastic medium. The

Asymptotic analysis of a problem for dynamic thermoelastic shells [PDF]
arXiv, 2020 In this paper we consider a family of three-dimensional problems in thermoelasticity for linear elliptic membrane shells and study the asymptotic behaviour of the solution when the thickness tends to zero.We fully characterize with strong convergence results the limit as the unique solution of a two-dimensional problem, where the reference domain is ...

Engineering Reports, Volume 7, Issue 5, May 2025.Synthesis, Characterization, and Evaluation of PVA/PANI/ZnO Composite. ABSTRACT Polyvinyl alcohol (PVA) and polyaniline (PANI) were mixed with zinc oxide (ZnO) nanoparticles, synthesized using the sol–gel method. A variety of PVA/PANI/ZnO nanocomposites were made using the solution casting approach with various ZnO concentrations (0.5, 1, 1.5, and 2 wt%

On the theory of thermoelasticity with microtemperatures
Journal of Mathematical Analysis and Applications, 2013 Abstract This paper studies the linear theory of thermoelastic materials with inner structure whose particles, in addition to the classical displacement and temperature fields, possess microtemperatures. We discuss uniqueness results within the context of the dynamic boundary value problems under very mild assumptions upon the thermoelastic profile ...

Elastic isotropy of hcp-Fe under Earth core conditions
, 2009 Our first-principles calculations show that both the compressional and shear waves of hcp-Fe become elastically isotropic under the high temperatures of Earth inner core conditions, with the variation in sound velocities along different angles from the c
