This paper presents the results of a dynamic analysis on unstiffened and stiffened corrugated panels subjected to hydrocarbon explosion. A parametric study is also conducted on simplified models of the stiffened corrugated panels considering the effect of stiffeners on the compressive flange under different loading levels. The $frac{1}{2}$ symmetry of corrugated panels is modeled. This numerical study is per-formed using NX Nastran version 7.5. The unstiffened panel produces localized buckling at the center of corrugation and large perma-nent deformation by increasing the peak pressure. The stiffened panels suppress the structural response, and the vee stiffeners are structurally more effective than the round ones.
