Molecular Dynamics Observation of Discreteness of the Mass Distribution During Nanoscale Fragmentation
Апстракт
Molecular dynamics simulations of the rigid-anvil collision test are performed by using a twodimensional
computational setup that mimics the traditional ballistic Taylor test. In this
extensively utilized computational setup, the slender nanoscale projectiles collide with a rigid
wall with hypersonic striking velocities ranging from 3 km/s to 30 km/s. The projectiles used in
these simulations are flat-ended, monocrystalline, nanoscale bars prepared at zero temperature.
The Poisson hyper-exponential distribution with the logarithmic binning is used to capture the
fragment mass (size) distribution under the constraint of the relatively small specimen size
15×100 nm. The objective is to highlight the occurrence of certain discreteness of the fragment
mass distribution observed both in time (during the fragment debris evolution) and across the
striking velocity field (for the final fragmentation states that correspond to the stationary
distributions).
