Description:
Precisely controlled extreme mechanical deformation, accompanying substantial plastic strains within the micro- or nanosecond regime, has gained growing attention for its ability to reveal novel physical and chemical behaviors of materials. These insights hold promise for advancing fields such as protection materials science, additive manufacturing, energetics, and mechanical metamaterials. Recent advances in microscopic ballistic methods utilizing high-velocity impacts of microparticles have facilitated fundamental studies of the dynamic responses of diverse materials, including soft matter, metals, and nanomaterials, under complex conditions involving nonlinearly coupled transient pressure and temperature. Microscopic ballistic techniqeus, including laser-induced projectile impact test (LIPIT), further enhance these studies by enabling highly localized deformation, facilitating high-resolution post-impact characterization and the discovery of novel materials by impact-induced thermodynamical nonequilibrium. Despite these emerging opportunities, research efforts in microscopic ballistics remains fragmented across disciplines.
This symposium aims to bridge these gaps by encouraging experimental and computational studies that focus on structure-property relationships, rate-dependent scaling laws, multi-scale computational modeling, material discovery, alignment with existing knowledge, and advancement in instrumental design.
