The goal of the project is to develop a method for calculating cyclic creep and long-term strength of structural elements of gas turbines and gas turbines engines. Research methods: methods of Solid Mechanics and Applied Mathematics, such as Theories of Plasticity and Creep, Continuum Damage Mechanics, Finite Element Method, finite differences methods of integration of initial problems, experimental. The models for Finite Element simulation of the creep of structural elements of turbines and gas turbine engines have been developed. Cycles of numerical analysis of creep and hidden damage accumulation in models of rotors, blades and blade locking joints under static and cyclic loading were carried out. Cyclic overloads, multi-cycle fatigue, and partial fracture during operation are taken into account. Experiments on creep and determination of macrostresses in metal specimens were carried out. An experimental unit for tests of creep and long-term strength of specimens and models was developed and manufactured. Product Description popup.authors Anishchenko Halyna О. Andrіeіew Yuriі M.
