Accidental explosions or bomb blasts cause extreme loadings on civilian and military structures. These structures have different curvatures, which affect their blast mitigation properties. Thus a controlled study has been performed to understand the effect of curvature on blast mitigation. The shock tube apparatus was utilized to obtain a controlled blast loading. Aluminum 2024 T3 panels having three different curvatures (infinity, 304.8 mm, and 111.76 mm) were used in the experiments. All the panels had un-deformed dimensions of 203.2 mm x 203.2 mm x 2 mm. A fully clamped boundary condition was applied. Digital Image Correlation (DIC) techniques were applied to obtain full-field in-plane and out-of-plane deformation data and in-plane strain on the back face of the panel. The results show that the panel with a 304.8 mm radius of curvature had a better blast resistance as compared to the other two panels.
