Abstrakt: Recently developed hybrid additive manufacturing techniques can create architectured composites where the constituents are patterned in a periodic array, with a characteristic length scale on the order of several hundred microns. This control over mesostructure can be used to fabricate materials with precisely controlled shock dynamics tailored for a specific response e.g., shielding, munition casing, etc. In the present work, we use hydrocode simulations to determine the structure of planar impacts in periodic two-dimensional composites and to assess their ability to dissipate shock compression. Additionally, localized, geometry-induced wave scattering is related to the bulk dispersive properties of the material. [ABSTRACT FROM AUTHOR]
