  A consistent stress-driven nonlocal integral model for nonisothermal
structural analysis of elastic nano- and microbeams is proposed. Most nonlocal
models of literature are strain-driven and it was shown that such approaches
can lead toward a number of difficulties. Following recent contributions within
the isothermal setting, the developed model abandons the classical
strain-driven methodology in favour of the modern stress-driven elasticity
theory by G. Romano and R. Barretta. This effectively circumvents issues
associated with strain-driven formulations. The new thermoelastic nonlocal
integral model is proven to be equivalent to an adequate set of differential
equations, accompanied by higher-order constitutive boundary conditions, when
the special Helmholtz averaging kernel is adopted in the convolution. The
example section provides several applications, thus enabling insight into
performance of the formulation. Exact nonlocal solutions are established,
detecting also new benchmarks for thermoelastic numerical analyses.
