Modeling and Simulation of Ceramic Arrays to Improve Ballistic Performance

reportActive / Technical Report | Accession Number: ADA603084 | Open PDF

Abstract:

Simulations were run on -Monolithic AI5083 -Baseline -Proposed seam design of thickened edges -Inefficient solution -Ceramic tiles with and without gap with the adhesive layer modeled -AutoDyn accurately models the behavior of the adhesive -Proposed seam design of step ladder -Reasonable possible solution AutoDyn material properties may need to be adjusted to capture the full damage that is occurring. Future work will include new seem designs, experimental testing and modeling done in LS-DYNA.
