This study concerns the analysis of a quasistatic frictional contact problem between a thermo-viscoelastic body and a thermally conductive foundation. The constitutive relation is built by a fractional Kelvin–Voigt model. The heat conduction is governed by time-fractional of temperature parameter $\theta$. The contact is described by the normal compliance condition and the friction is described by Coulomb’s law. We derive a variational formulation of the problem and prove the existence of a weak solution to the model by using the theory of monotone operator, Caputo derivative, Clark subdifferential, Galerkin method and Banach fixed point theorem.
