Modified DPL Green–Naghdi theory for thermoelastic vibration of temperature-dependent nanobeams

Results in Physics, 2020
A unified multi-dual-phase-lag thermoelasticity theory is presented to study the vibration of a temperature-dependent nanobeam subjected to a ramp-type heating. The nonlocal thermoelasticity theory based on Euler-Bernoulli hypothesis is applied.

Refined Green–Lindsay Model for the Response of Skin Tissue under a Ramp-Type Heating

Mathematics, 2023
Based on Green–Lindsay generalized thermoelasticity theory, this paper presents a new refined higher-order time-derivative thermoelasticity model. Thinner one-dimensional skin tissue is considered when its inner surface is free of traction and does not ...

Generalized Lagging Response of Thermoelastic Beams [PDF]

Mathematical Problems in Engineering, 2014
The vibrations of Euler‐Bernoulli metal beam are accommodated in the present study by taking into account the possibility of activating the microstructural effects, captured by the temperature gradient phase lag, in the fast transient process captured by the heat flux phase lag.
