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
