Deformation and Damage of High Temperature Structural Elements at Cyclic Loading

Due to the development of new designs and materials for engines and turbomachines, which are characterized by elevated operating temperatures, it is necessary to estimate the level of irreversible creep strains and the possibility of fracture. In contrast to the previously created general-purpose methods, calculation methods which currently are developed, are aimed at analyzing specific structural elements from specific steels.

The focus of the project is on development a method for calculating cyclic creep and long-term strength and numerical study of the behavior of structural elements operating under the combined action of thermal fields and loads.
