“…Their observations indicate that the closest FE displacement curve to the experimental one was obtained in case of JC2 (spatial distribution of load). They justified this observation as a result of relatively slow propagation of the blast load in air, so there is a delay in arrival of the blast wave to different points of the panel (Cichocki and Ruchwa 2000).…”

In combat operations, naval ships may be subjected to considerable air blast and underwater shock loads capable of causing severe structural damage. As the experimental study imposes great monetary and time cost, the numerical solution may provide a valuable alternative. This study emphasises on numerical analysis for optimization of stiffened and unstiffened plate's structural response subjected to air blast load. Linear and non linear finite element (FE) modeling and analysis was carried out and compared with existing experimental results. The obtained results reveal a good agreement between numerical and experimental observations. The presented FE models can eliminate confusion regarding parameters selection and FE operations processing, using commercial software available currently.
