Description

The designing of strength for ceramic turbine wheels has been carried out by the finite element method as the best way. It is still necessary, however, to detect a fracture origin to study the correlation between the calculated values of stress and fracture of wheels. However it is difficult to detect the fracture origin of the ceramic wheels by inspecting the fragments since they break into small pieces. Two detective methods of fracture origin of the ceramic turbine wheels are reported in this study. One is the method to take photographs at a fracture moment, and the other is to observing the fracture surface by restoration of wheel using photographs.
