    Abstract

    This paper discusses the development of a new technique for measuring the strength of ceramic shells. In this technique, compressed air was passed into the ceramic shells and the bursting pressure was measured using a diaphragm pressure gage. The hoop stresses were calculated. The results of the new technique realistically match the actual failure rate of shells in the precision casting process.
