Abstract
This paper presents a constitutive equation for no-tension materials in the presence of thermal
expansion that accounts for the temperature-dependence of their material's constants.
Specifically, under the hypothesis of infinitesimal strains, an explicit expression is given for free
energy from which the internal energy, entropy and stress are obtained. Then, the basic equations
of the thermo-mechanical equilibrium of a no-tension solid are presented, and we observe that if
the strain rate is small thermo-mechanical uncoupling occurs. Finally, the solution to the
equilibrium problem of a circular ring made of a no-tension material subjected to a plane stress
under the action of both two uniform radial pressures exerted on the inner and oute
