For the issues of a large number of geometric variables,hard to select geometric random variables and determine their probability distributions,rebuilding the finite element model in an automated fashion,and huge numerical computation comsuption when conducting the LCF(low cycle fatigue)life prediction considering geometric uncertainties of turbine disk.A geometric uncertainty probabilistic processing method was proposed.First,the design of experiments method was employed to determine key geometric paramete...
