Abstract
The lifetime of turbine discs under complex non-proportional thermo-mechanical cyclic loading is analyzed by means of the direct finite-element simulation of deformation and fracture processes using thermo-elasto-visco-plastic material model and deformation failure criterion. A good agreement is observed in comparison of the obtained number of cycles to macrocrack initiation with experimental results for five turbine discs made from different materials and subjected to various loading conditions.
