A. N. Servetnik
CIAM, Russian Federation

Keywords: spin disk testing, burst speed, fracture criterion, strain energy density

FE modeling of burst speed tests of gas turbine engine disks using stress-strain properties confirmed by tensile tests of specimen was carried out. Burst speed test results of various disk configurations and thermo-mechanical loadings were compared with three-dimensional elastic-plastic FEM analysis results using energy-based method
