N2 - This paper extends the single degree of freedom (SDOF) equations of motion for a rigid plastic, rectangular plate subjected to moderate pressure loading to one Impacted by more intensive loading. As a result, the assumed roof shaped deflection pattern, with four symmetric, rigid triangular and trapezoidal regions separated by plastic hinges, becomes more box shaped. That is, a fifth centralized, rigid rectangular region forms between the original regions. Moreover, elastic effects are considered to better model the final deformed shape of a thin panel luggage container subjected to an internal bomb blast. Results from the current method are compared with finite element solutions and published experimental data for maximum and permanent plate deflection.
