Resumo: The integro-differential equation governing the isothermal creep rupture behaviour of a kinematically determined two-bar structure under steady load is derived and solved in analytical form. One of the bars is described by an elasto-creep material model that accounts for the three phases of creep deformation and for the full coupling between the creep deformation and damage processes. The second bar is assumed to have a linear elastic behaviour. The non-linearity of the constitutive equations and the stress redistribution induced by the development of creep damage are the major physical features dealt with in this study. Numerical applications illustrate the mathematical features of the analytical solution obtained.
