We develop computational models aimed at the determination of the residual service life of two-layer plates with systems of cracks under long-term static loads at high temperatures. The models are based on the first law of thermodynamics of energy balance for the components and rates of their changes in a metallic two-layer body containing macrocracks and subjected to the action of long-term tension and high-temperature fields. We consider periodic and doubly periodic systems of cracks.
