Abstract: Because of explosion complexities, the investigation on quasistatic pressure after explosion was very scarce. But it was the foundation for safety assessment and failure analysis of explosive containment vessels (ECV). For studying quasistatic pressure in ECV, a reusable ECV of 195 mm in inside diameter and 8.87 kg/m3 in the largest charge density ratio (Q/V) was designed. The static pressure timevarying law and the fitting equation bwtween quasistatic pressure and charge density ratio were obtained experimentally. The results show that there exists a quick increasing—exponential decreasing—rerising—quasistatic process.
