Ballistic Impact Dynamic Modeling of Fabric for New Protection Systems

Advanced Computation and Engineering Services proposes to develop new and innovative modeling concepts to more accurately define and predict the failure modes of various fabric materials from current and futuristic ballistic impacts, working closely with North Carolina State University and conferring with engineers at body armor manufactures. Extensive research has been conducted by various government laboratories and universities to accurately model the ballistic response of fabrics. However, these research efforts have not produced a general design tool that will assist in the design of ballistic protection systems. This proposal seeks to combine and extend the work of previous researchers to demonstrate the feasibility of a new design tool for ballistic protection systems. Instead of attempting to develop a single modeling method to address the dramatically different needs of a designer, this proposal uses a range of methods. Within this tool, the designer will be capable of conducting detailed modeling of the individual yarns and global modeling of the entire protection system. Thus, this design tool will support a wide range of needs by using different numerical methods. At the conclusion of Phase 1, feasibility of the design tools will have been demonstrated.
