In this paper, the interaction between holes and electrons in semiconductor media is analyzed based on existing mathematical–physical model. The elasto-thermodiffusion (ETD) theory, according to photothermal (PT) transport processes, has been used study model under impact of non-Gaussian laser pulse. A one-dimensional (1D) electronic/thermoelastic deformation described, detail, by governing fie...

Plane time-harmonic waves with assigned wavelength are supposed to propagate in an infinite linear thermoelastic space: The thermodynamic response is framed into the time differential dual-phase-lag model, while Cowin–Nunziato theory used depict effect of porosity for elastic part. We able show that it possible identify two shear waves, undamped and not affected by and/or temperature, as well f...

Thermoelastic modeling at nanoscale is becoming more important as devices shrink and heat sources are widely used in modern industries, such nanoelectromechanical systems. However, the conventional thermoelastic theories no longer applicable high-temperature settings. This study provides an insight into thermomechanical features of a nonlocal viscous half-space exposed to cyclic source. Using n...

This paper aims to present a Lord-Shulman theory of one relaxation time and the dual-phase-lag model two-relaxation times study effect gravity on both micro-elongated thermoelasticity layer elastic in above. The normal mode analysis was used obtain expressions displacement components, micro-elongational scalar, stress components. Comparisons between physical quantities were getting numerically ...

We analyze an extension of the dual-phase lag model thermal diffusion theory to accurately predict contribution thermoelastic bending (TE) Photoacoustic (PA) signal in a transmission configuration. To achieve this, we adopt particular case Jeffrey’s equation, Generalized Cattaneo Equations (GCEs). Obtaining temperature distribution by incorporating effects fractional differential operators enab...

Carbon fiber-reinforced plastic (CFRP) is widely used for structural members of transportation vehicles such as automobile, aircraft, or spacecraft, utilizing its excellent specific strength and specific rigidity in contrast with the metal. Short carbon fiber composite materials are receiving a lot of attentions because of their excellent moldability and productivity, however they show complica...

This paper estimated the problem of one-dimensional generalized thermoelastic half-space in medium considering two models: Lord and Shulman (LS) model Dual-Phase-Lag (DPL) model. We assumed that surface was free from traction force under an exponentially varying external heat source at boundary with time. The technique homotopy perturbation has been applied to find approximate solution for inte...
