Аннотация: The stress-strain state is considered and the time until the destruction of a composite tensilerod during creep is determined. The rod consists of three parts arranged symmetrically in thickness. An additional condition is accepted: all parts of the composite rod are rigidly interconnected without slipping. The creep of each part of the rod is described by a power model with different parameters.To determine the time to failure, a kinetic equation is used that describes the accumulation of damage during the creep process. For each part of the rod, the same form of the kinetic equation is adopted, but the accumulation of damage occurs under the action of stresses that are different for each of the parts. Stress distributions and processes of damage accumulation in time in various parts of a composite rod are analyzed. The values of the material constants in the power laws of creep and long-term fracture are determined, leading to an increase in the time until the destruction of the composite rod
