TL;DR: In this article, free vibrations of nonhomogenous (functionally graded material (FGM)) axisymmetric nonlocal thermoelastic hollow sphere has been taken into consideration for investigation.
Abstract: Free vibrations of non-homogenous (functionally graded material (FGM)) axisymmetric nonlocal thermoelastic hollow sphere has been taken into consideration for investigation The material of nonlocal thermoelastic sphere is supposed to be graded using power law in radial direction The solution of continued power series is employed to resolve the differential equations and to investigate the analytical solutions for field functions ie temperature, stress and displacement The analytical results have been authenticated using numerical computations with computer based software like MATLAB The numerical results have been shown graphically for the comparison of frequency shift and thermoelastic damping for local and nonlocal elastic materials Deduction of results has been validated with the already published literature

TL;DR: In this article, the analysis of transient wave characteristics in a functionally graded viscothermoelastic infinite medium with spherical cavity in the context of generalized thermelasticity is presented.
Abstract: This paper aims to present the analysis of transient wave characteristics in a functionally graded viscothermoelastic infinite medium with spherical cavity in the context of generalized thermoelasticity Continued series solution is used to solve simultanious differential equations for evaluating the field variables Convergence of the series solution is implemented and investigated that the series of functions are absolutely and uniformly convergent The formal solution for the field variables are obtained analytically and represented graphically The effect of grading index and different theories of generalized thermoelasticity are also shown graphically to examine the behavior of the variations of the field variables

TL;DR: In this article, the Lord-Shulman theory of generalized thermoelasticity based on a memory-dependent derivative is employed to study the thermo-elastic response in a three-dimensional elastic half-space medium whose free surface is assumed to be traction-free and subjected to a thermal shock.
Abstract: The Lord–Shulman theory of generalized thermoelasticity based on a memory-dependent derivative is employed to study the thermoelastic response in a three-dimensional elastic half-space medium whose free surface is assumed to be traction-free and subjected to a thermal shock. The numerical solutions for the field variables are presented graphically and analyzed for various values of the time delay parameter. The predictions of the new model are discussed and compared with the Lord–Shulman model (without memory-dependent derivative).
