  An effective nonlocal integral formulation for functionally graded
Bernoulli-Euler beams in nonisothermal environment is developed. Both thermal
and mechanical loadings are accounted for. The proposed model, of stress-driven
integral type, is shown to be governed by a thermodynamically consistent
differential problem with proper constitutive boundary conditions. The new
thermoelastic strategy is illustrated by investigating a set of examples. It is
demonstrated that in nonisothermal statically indeterminate problems rather
complex structural behaviours can appear and that both the shift of the neutral
surface and nonlocality have a dominating influence at small-scales.
