Recent advances in generalized thermoelasticity theory and the modified models: a review

Abstract

A review of the recent studies on the generalized thermoelasticity theories and their associated modified models is presented. The aim is to outline an overview of the utilization and physical limitations of available relevant theories. By contrast to classical thermoelasticity theory, generalized thermoelasticity theories (second sound) can involve a hyperbolic-form transport correlation and are motivated by experiments illustrating more accurately of the wave-form heat transfer (second sound). Many researchers have formulated such theories on different fields and analyzed various problems, presenting characteristic properties of these theories. This paper expresses a self-included bibliographical review of previous documents in the area of the second sound. The general structure of this review contains theories, formulations, real limitations, and used solution techniques of the equations for different geometries and loadings. Given that the classical theory is feeble in simulating the temperature distribution, especially in the structures under a sudden thermal shock, this review may be a useful tool for researchers who work in sensitive industries such as steam turbines, micro-temperature sensors, and lithium battery manufacturing.

Challenges and limitation of wearable sensors used in firefighters’ protective clothing

“…41,42 In recent decades, the thermophysiological effects of personal protective devices on firefighters have been investigated and analyzed in the laboratories. 43 Higher heat load can pose thermal stress, [44][45][46][47] leading to thermal exhaustion, loss of consciousness, physical fatigue, mental confusion, and dehydration influencing danger perception and productivity. To control and avoid thermal shock in firefighters, a continuous and reliable temperature sensor that is capable of assessing the real-time core temperature of firefighters' body is necessary.…”

Effect of loading rate on transient response of a nano scale medium based on continuum and thermal conduction nonlocal model

“…u is the components of the displacement vector,  is the nonlocal term, 12 ,  are the relaxation time term, β = (3λ + 2μ)α, α is the coefficient of linear thermal expansion, C is the specific heat, λ, μ are Lamé constants and ρ is the mass density [30][31][32]. In this situation, the stress at a meticulous location of the medium depends on both the strain at that point and its surroundings of other points of the medium.…”

A review of size-dependent continuum mechanics models for micro- and nano-structures

“…Various mechanical behavior can be addressed under different external loadings, which can affect noticeably stiffness, stress, strain, and deformation of the micro/nano-structures. Therefore, the importance of investigating the effects of Fourier/non-Fourier heat conduction, coupled thermoelasticity analysis including the classical coupled and Lord-Shulman coupled models, uncoupled magneto-thermoelasticity analysis, as well as electro-thermoelasticity behavior is essential on the mechanical behavior of micro/nano sized-structures [210][211][212][213][214][215][216][217][218][219][220][221][222][223][224][225][226][227][228][229].…”
