The failure analysis of a fly through frangible canister cover is studied based on transient dynamics via the finite element method. The cover, which is fabricated with five plan-liked parts, is cohesively bonded together forming several weak paths. Five test specimens are designed according to the length of bonded fiber cloth. The cover is subjected to an impulsive blast and the failure process is obtained and analyzed. The failure pressure and time are determined at different cloth length. The result shows that the failure pressure and the corresponding time rise as the length of bonding layer increases.
