Fracture of Steel in Energy Machine Parts: High-Temperature Creep and Hydrogen Influence presents advanced mathematical modeling approaches for evaluating the effects of high-temperature creep, hydrogen diffusion, damage accumulation, and creep development in steam pipelines, steam turbine discs, heat exchanger tubes, and steam boiler drums. The book discusses the strength and durability of metallic materials and structural elements at the stage of volumetric damage, then at local damage, and, finally, at the end of their residual life. It introduces models and algorithms for simulating these complex processes (high-temperature creep, hydrogen diffusion, damage accumulation, and creep development) that evolve at different rates in different areas of a structure. The various types of cracks are addressed, including through-thickness cracks, internal cracks, surface cracks, and elliptical cracks.
