The present pa.er dea.s with thermoela.tic problems of finitely long hollow cylinder com-posed of two different ma.eria.s with a.ia. sym- metry. The medium is tra.tion-free, with neglig-ible body forces a.d with interna. a.d externa. hea. genera.ions. The governing equa.ions for different theories of the genera.ized thermoe-la.ticity a.e written in terms of displa.ement a.d tempera.ure increment. The exa.t solution of the problem;using different theories of genera.ized thermoela.ticity;ha. been deduced. The a.a.ytica. expressions for displa.ements, tempera.ure a.d stresses a.e found in fina. forms, a.d a.numerica. exa.ple ha. been ta.0}n to discuss the effect of the rela.a.ion times. Fina.ly, the results ha.e been illustra.ed gra.hi- ca.ly to find the responses of different theories.
