Fracture phenomena of plate and dome shaped specimens using a shock tube for glass‐filled ceramics were investigated. Glass‐filled ceramics have been considered a promising candidate material for the dome port cover of an air breathing engine. This part of the air breathing engine has an important role in separating solid and liquid fuel, and needs a frangible characteristic that the fracture of a part should not affect the internal components of combustion. The objective of this study is to evaluate the fracture pressures for various thicknesses and diameters of the shock impact area. Also, fracture phenomena of separated membrane using a shock tube are compared with a numerical method. The experimental apparatus consists of a driver, a driven section and a dump tank. The used material is a glass‐filled ceramic made from Corning Company. Specimens are used with 3, 4.5 and 6 mm thicknesses, respectively. It is expected that the results obtained from this study can be used in the basic data for the dome port cover design of an air breathing engine.
