EXTREME DYNAMICS OF NANOMATERIALS UNDER HIGH-RATE
MECHANICAL STIMULI

Nanomaterials demonstrate novel mechanical properties attributed to the extremely
large interfacial area. At quasi-static rates, the interfacial interactions are crucial in
mechanical behaviors, however, materials under extreme mechanical stimuli are rarely
studied at nanoscale. With an advanced laser-induced projectile impact test, we perform
supersonic impact of micro-projectiles on polymer films, multilayer graphene, carbonbased
nanocomposites membranes as well as individual micro-fibers, to study the interface
interactions in the high-rate regime, and develop a simplified model to characterize the
ballistic performance of materials.
