For enhancing the explosion resisting performance of the outer structure, the dynamic response of plates with different stiffeners under the explosion loading is numerically simulated. The plates are with their four sides fixed. Finite element models for four kinds of plates are built using the ABAQUS software, to simulate the dynamic response. The energy distribution, the maximum deflection at the plate center and the stress distribution are analyzed and compared. To resist the explosion loading, the increased number of stiffeners does not mean a better performance. Among the four plates with different stiffeners, the triangle stiffener coupled plates are the best one for the anti-explosion performance.
