The transient response of steel panels subjected to close-in impulsive loadings is being investigated concerning the vulnerability of naval ships to near field high explosive detonations. The first objective of the study is to find the failure modes of a panel depending upon variations of the explosion stand-off and mass. The second objective is to predict the transient response and failure of a panel subjected to an explosive loading. In order to meet these objectives close-in explosion experiments were performed and a numerical model was being developed using an existing finite element code (LS-Dyna) implemented with an improved material model.
