Abstract : This study is concerned with the numerical study of fully fixed stiffened plates. The aim of this research is to determine the dynamic response of the plates with different stiffener configurations and considering the effect of standoff distance. Numerical solutions are obtained by using the finite element method and the central difference method for the time integration of the nonlinear equations of motion. Special emphasis is focused on the evolution of mid-point displacements, von Mises stresses and strain energy vs. kinetic energy. The results obtained allow an insight into the effect of stiffener configurations and of the above parameter on the response of the plate under uniform blast loading and indicate that stiffener configurations, standoff distance and time duration can affect their overall behavior. From the study, it is observed that the stiffeners effectively sustain the blast pressure, and the cover plat with HAT stiffener can sustain stresses more than the plate with T and I stiffener, and are deformed with less relative displacement.
