The book "Characteristic Analysis on Thermoelastic Micro-continuum Solid" provides a comprehensive investigation of the characteristic analysis of thermoelastic and thermodiffusive micro-continuum materials. It addresses various types of waves and their properties in different phases of the analysis. A central theme is the introduction of the fractional-order generalized heat conduction equation in micropolar thermoelasticity, which takes into account both the conductive temperature and the thermodynamic temperature. Additionally, a generalization of Fick's law is integrated into the literature. The book illustrates the propagation of plane harmonic waves considering thermoelastic diffusion and examines the response of various heat sources in differently positioned micro-continuum materials. It is a valuable resource for researchers in the fields of elasticity, thermoelasticity, and wave propagation.
