Generalized thermoelasticity of microstructures: Lord-Shulman theory with modified strain gradient theory

Jaber Alihemmati et al.

Summary: In this study, the general form of coupled thermoelasticity for microstructures is derived by combining the Lord-Shulman thermoelasticity theory with the modified strain gradient theory. The developed model is applied to a one-dimensional microlayer and the governing thermoelasticity equations are derived based on both theories. The effects of length scale parameters on displacement, stress, and temperature distribution are investigated using a consistent Chebyshev collocation method.

A rate-dependent constitutive model of piezoelectric thermoelasticity and structural thermo-electromechanical responses analysis to multilayered laminated piezoelectric smart composites

Chenlin Li et al.

Summary: This study presents a novel rate-dependent piezoelectric thermoelasticity model applied to multilayered laminated piezoelectric smart composites. The study reveals that selecting appropriate thermal/strain/electric relaxation time parameters or considering non-idealized boundary conditions can greatly enhance the performance of the composites.

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

Farshad Shakeriaski et al.

Summary: This review provides an overview of recent studies on generalized thermoelasticity theories and their modified models. Contrasting with classical thermoelasticity theory, generalized thermoelasticity theories offer more accurate descriptions of heat transfer, particularly in structures subjected to sudden thermal shocks. Researchers have developed and analyzed these theories in various fields, demonstrating their unique properties and application potential.
