Modeling of Thermomechanical Processes in Energetic Equipment Elements Under In-Service Conditions and Estimation of their Operational Life with Accounting for a Material Degradation, Damages and Repair Procedures

Section: Scientific and Technical Innovative Projects of National Academy of Sciences of Ukraine
Language: Ukrainian
Abstract: Approach for computer simulation of deformation processes in power equipment elements under exploitation with regard of material degradation, shape of operational damages or change of element shape after repair based on three-dimensional elastolasticity is proposed. The stress-strain state of high pressure boiler drum and connecting pipes with repair excavations of material defects, collectors with cracks and waterwall tubes with operating thinnings are investigated. The recommendations are used in the development of repair technology and estimation of operational resource of power equipment elements at the Burshtyn TPP.
Key words: mathematical and numerical simulation, strength and operational life.
