Fracture Evaluation in a Ceramic Spherical Dome Port Under Shock Impact

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… Show more

“…Recently, shock tubes have been used to study the response of several composite materials like glassreinforced polymers and 3-D woven composites [19,20]. Even a fracture investigation of a ceramic spherical dome was carried out with a shock tube device [21], as well as the response of a stainless steel panel and the influence of the connection detail [22]. The original features of the shock tube here presented are strictly related to its unusual applications and consist in a proper choice of the main parameters characterizing the facility design able to guarantee a high pressure range (~3 MPa), a suitable end-chamber designed to investigate soil-structure interaction as well as proper burner equipment to heat concrete specimen intrados following a defined fire curve.…”
