Introduction The theory of thermoelasticity for elastic materials with microtemperatures, whose particles contain a displacement vector and temperature field, was established by Grot [11]. Eringen developed the theory of micromorphic bodies and the theory of thermo-microstretch elastic solids. An extensive review and basic results in the microcontinuum field theories for solids (micromorphic, microstretch, and micropolar) including electromagnetic and thermal interactions are given in his works [9,10]. In [16], Ieşan and Quintanilla formulated the boundary value problems of the theory of thermoelasticity with microtemperatures and presented a unique result and a solution of Boussinesq–Somigliana–Galerkin type. The theory of micromorphic elastic solids with microtemperatures was presented by Ieşan in [12,15]. In [18], Ieşan and Quintanilla discussed various problems using thermoelasticity with microtemperatures. Many investigators studied different types of problems for thermo-microstretch medium in detail (some of those works can be seen in [1-8,13,14,17,20-24,26,27] and the references therein). The
