Polyurea composites have been considered as a self-healing and anticorrosion coating in building applications,and more interestingly, as a lightweight addition to steel armor. In combination with a metal plate, a polyurea layer has been extensively studied under impact and blast loading. In this research, the tunable performance of polyurea sandwich armor composites is explored in modeling and experimentation. Cylindrical arrays comprised of polyurea, a resilient yet dissipative material, enable improved load transmission by utilizing new dissipation and storage pathways due to geometry. Experimentation and computational modeling are used to quantify the dissipatio features of the polyurea composite. This research combines a new polyurea interlayer geometry with steel to improve the composite armor blast performance by increasing energy dissipation.","abstract_html":"Polyurea composites have been of interest for a variety of engineering applications for their highly dissipative yet resilient behavior under deformation.
