Ceramic Life Prediction Methodology - Hot Spin Disc Life Program

Abstract

A rotating disc was designed to fail due to time dependent mechanisms. Several discs were fabricated and an existing test rig was developed to test the discs at design conditions. Ten discs were tested at steady state under the design conditions of 2300 F rim temperature and 50,000 rpm for periods of 0.20 hours to 25 hours. An experimental failure distribution was obtained for the ten discs and presented as reliability versus time. Three different data bases (double torsion, stress rate, and stress rupture) were used to calculate reliability versus time and the results were compared to the experimental results. It was observed that the best correlation with the experimental results was given by the stress rupture data base.
