<p>This is the third and final work in a series dedicated to thermoelastic arched beams of Bresse type under Fourier’s law. Herein, our first main goal is to provide a detailed modeling of the thermoelastic Bresse–Fourier systems, addressing thermal couplings and their effects on axial, shear, and bending forces. Then, the stability results are rigorously analyzed, by proving that stability patterns remain consistent under different boundary conditions and thermal couplings. Theoretical contributions include semi-uniform algebraic and uniform exponential decay rates, achieved using semigroup theory. This paper concludes the trilogy by unifying the stability analysis for all remaining systems with new thermal couplings.</p>
