Investigation of the influence of boundary conditions and degradation factor of the surface layer on the GTE structural elements stress-strain state
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 88, Issue 4
Abstract
The influence of the boundary conditions of the nonstationary thermal cyclic loading and degradation of the material surface layers on the stress-strain state of the material of the wedge-shaped specimens, which model the gas-turbine engine blade edge, is shown using the methods of physical and mathematical modeling with the presence of crack-type defects. The necessity of the investigation of structural changes and properties of the material, thermal and thermal-deformed state of the material is demonstrated to determine the possibilities of safe extension of the given lifetime of the equipment and assurance of efficiency as well as reliability of energy systems.
