Wave propagation in dual-porosity media under the combined effects of light, heat, elasticity, and gravity

| Nature Verified
Abstract This paper investigates the propagation of two-dimensional thermoelastic waves in a semiconductor medium characterized by double porosity and subjected to the influence of gravity. We develop the theoretical framework using the Lord–Shulman (L–S) and Green–Lindsay (G–L) models. Both models account for finite thermal wave speeds and relaxation times.

Moisture Photo-Thermoelasticity Diffusivity in Semiconductor Materials: A Novel Stochastic Model

By Alaa A. El-Bary, Ramdan S. Tantawi, Abdulaziz Alenazi, Abdelaala Ahmed
| MDPI
Abstract : A unique methodology due to the effect of stochastic heating is utilized to study the Moisture Diffusivity influence of an elastic semiconductor medium under the effect of photo-thermoelasticity theory. Accurately, random processes are applied at the boundary of the semiconductor medium. The governing equations are expressed in the one-dimensional form (1D). The boundary conditions are considered random; the additional noise is regarded as white noise.
