摘要: In the present study, dynamic behavior of two types sandwich composites made E-Glass Vinyl-Ester (EVE) face sheets and Corecell TM A-series foam with a polyurea interlayer was studied using shock tube apparatus. The materials, as well core layer arrangements, were identical, only difference arising in location interlayer. itself layered based on monotonically increasing wave impedance layers, lowest facing loading. For configuration 1, placed behind front sheet, core, while 2 it back sheet. A high-speed side-view camera system along back-view Digital Image Correlation (DIC) utilized to capture real time deformation process mechanisms failure. Post mortem analysis also carried out evaluate overall blast performance these configurations. results indicated that applying sheet will reduce deflection, particle velocity, in-plane strain, thus improving maintaining structural integrity.
