Modelling and Assessment of Additively Manufactured Materials under Extreme Dynamic Stresses
Abstract
Additively Manufactured (AM) components enable unique opportunities in everything from component manufacturability to unique and tailor-able behaviors. The possibility of anisotropic response means that AM components may have an entirely different response to dynamic stresses than the corresponding monolithic parts. One area where this could be particularly true is in shaped charges (SCs) and explosively formed projectiles (EFPs). Current (SC) designs are based upon effective jet generating designs that are “easily” manufactured with current machining equipment; typically in the form of cones of different half angles. Additive manufacturing enables the ability to modify the design to generate the best penetrating jet or formed projectile without concern of its manufacturability. Furthermore, it could provide implementation of non-monolithic material schemes to further enhance jet formation and performance. Purdue University Energetics Center (PERC) seeks to partner with CAMRE in order to explore the responses of AM materials under explosively driven stresses, specifically with regards to SCs/EFPs. CAMRE PI will serve as the component manufacturing arm and PERC PIs will serve as the testing/modelling arm of the partnership. In this effort, CAMRE and PERC will seek to initially match performance of current SCs using simplified printing geometries (e.g. cone). From there, CAMRE and PERC will explore other SC/EFP designs as well as general AM dynamic responses under explosive conditions.
