| A particular challenge in material sciences is the design and synthesis of molecular structures with desired physical properties. Atomistic simulations using MD techniques play a crucial role in this task. Here we present, at the atomic scale, first results and intended general methodology in the study of wave propagation and response to high shock loading for different materials. We have studied different materials ranging from single crystal structures to more complex nanostructures (nanocrystals). We report non-equilibrium Molecular Dynamics simulations, using empirical MEAM potentials, that are able to cover similar times and length scales as laser-shock experiments. Our results try to fill the present gap providing atomic information in detail for the mechanisms of lattice deformation, plasticity, dislocations and relaxation in the response to wave propagation. New nanostructured materials, such as nanocrystals, and porous metals (metallic foams), are the perfect candidates to take part in different critical components in a Fusion reactor. For instance, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory will require polycrystalline ignition targets. On the other hand, metallic foams appear as a possible alternative in current designs for targets in the HiPER initiative. We are not only trying to evaluate their behavior under shock loading conditions but also discuss their suitability as future compounds in the present and future scenario of Nuclear Fusion Technology. | |
