The subject deals with elementary theoretical and practical knowledge from region behavior of materials and constructional elements under elevated temperatures, when the creep or relaxation is situated. These are problems of classical and nuclear energetic (boilers, pipeline, generators, parts of gas engine). There are including the basis from physics of materials, testing of materials, life-time prediction, etc.
Primary, secondary and tertiary creep. Dislocation and diffusion creep models. Stress-strain relations. L-M parameters. Creep mechanism identification, Activation energy, Hoff analogy.
