Elastic Thermal Deformation of an Infinite Copper Material Due to Cyclic Heat Supply Using Higher-Order Nonlocal Thermal Modeling

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 However, the conventional thermoelastic theories no longer applicable high-temperature settings.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 novel concept fractional derivatives, introduced by Atangana Baleanu, it assumed that viscoelastic properties follow Kelvin–Voigt model. The differential form Eringen’s theory employed consider impact small-scale behavior. It also proposed rule dual-phase thermal conductivity can be generalized materials include higher-order time derivatives. numerical results for examined physical variables presented using Laplace transform technique. Furthermore, several analyses performed in-depth, focusing on effects nonlocality, structural indicator, order, phase-lag parameters behavior half-space. According findings, appears terms have major reactions may work mitigate diffusion. these provide approach categorize based their conductivities.
