Abstract :
Ceramic is one of promising materials for pressure housings because ceramic has higher compressive strength than titan alloys. However, as the tensile strengths of ceramics are only a fraction of the compressive strength, common design methods for pressure housings of metals can not be directly applied to ceramic pressure housings. We will propose a new design method to coupling ceramic hemisphere and cylinder, and confirmed its validity with finite-element method analysis. We made a small-sized model of a pressure housing and examined that it can stand external 120 MPa water pressure.
