Generalized Thermoelastic Phenomena in Functionally Graded Materials
Summary
Functionally graded materials (FGMs) exhibit spatially tailored microstructures that enable continuous variation of mechanical, thermal and electrical properties. Generalized thermoelastic theories extend classical formulations by incorporating thermal relaxation times, finite propagation speeds and energy dissipation mechanisms, thereby capturing wave-like heat transport and coupling effects absent from Fourier-based models. In FGMs, graded distributions—often described by power-law or exponential functions—mitigate stress concentrations and thermal mismatches under dynamic or shock loading. Theoretical treatments invoke diverse frameworks such as Lord–Shulman dual-phase-lag, Green–Naghdi type II and III, and non-classical formulations that account for microstructural inertia. Analytical solutions for plates, shells, cylinders and spheres typically employ eigenfunction expansions, matrix methods and potential theories, while numerical approaches integrate layerwise differential quadrature, non-uniform rational B-splines and finite difference schemes. Across applications in aerospace thermal shields, energy-harvesting sensors and biomedical implants, advances in modelling generalized thermoelastic interactions in FGMs have illuminated the interplay between graded composition, thermal wave phenomena and electromechanical coupling.
