Abstract
In this study, a fracture evaluation of a ceramic spherical dome port under shock impact has been presented. The experiments were carried out with a shock tube device capable to produce a normal shock. The pressure behind the normal and reflected shock wave was predicted by analytic equations based on initial conditions. The pressures were measured by embedded dynamic pressure sensors. The fracture of specimen was occurred by the pressure behind the reflected shock wave. The pressure distribution in shock tube was obtained during 0 to 5 ms. Simultaneously, the distributions of the pressure, temperature and velocity were calculated in the shock tube at 3 ms after diaphragm burst for various thickness of dome port. The results of numerical analysis and analytic solutions were good agreement with experimental results.
