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 mesh density, time duration and strain rate sensitivity. Numerical solutions are obtained by using the finite element method and the central difference method for the time integration of the non linear equations of motion. Special emphasis is focused on the evolution of mid-point displacements and plastic strain energy. The results obtained allow getting an insight into the effect of stiffeners configurations and of the above parameters on the response of the plates under uniform blast loading and indicate that stiffener configurations and time duration can affect their overall behaviour.
