material analyses and life assessment:

  • Tools for strength design of compressor and turbine radial wheels
  • Research on thermomechanical properties of materials and structures of blade/wane machines, including the effects of high temperatures
  • Development of prediction tools and experimental methodologies for determination of thermo-mechanical loading and fatigue of structures
  • Development of software tools for multiaxial fatigue
  • Development of software for complex prediction of thermomechanical fatigue with time-dependent processes based on FEM analysis
  • Development of predictive tools for determination of aero-thermodynamic load, development of software for aero-thermodynamic model of gas turboprop engine up to 2MW (Gas pathway analysis-model)
  • Investigation of the effects of various types of mechanical and physical damage on the function of turbomachinery
  • Software development for engine prediction and wear of individual parts based on neural networks and fuzzy logic
  •  Thermomechanical fatigue based on a stable stress-strain state
  • Calculation of low and high cycle fatigue of rotating parts, multi-axis fatigue, assessment of actual load spectra
  • Calculation of creep and calculations of creep life in combination with low cycle fatigue
  • Calculation of thermal-mechanical strength based on stabilized deformation stress

 

Equipment:

  • TMF_PRED software - determines the residual life of the component stressed by mechanical and thermal loads
