Experimental investigation on dynamic response and fracture characteristics of discrete multilayered thick-walled explosion containment vessels

A discrete multilayered explosion containment vessel (DMECV) mainly consists of covers, inner shell and steel ribbon layers crossly helically wound on the inner shell. Three DMECV with the same materials and dimensions except helical winding angle were fabricated and used to investigate dynamic response and fracture characteristics of DMECV subjected to internal blast loads at the center. All tested DMECV are damaged in the cylindrical portion near the explosion center. The DMECV with smaller ribbon winding angle has better capacity for withstanding internal explosion. Results also show that DMECV have excellent explosion resistance.
