Elastic Behavior of Spherical Nanodroplets in Head-on Collisions
S Kim, JOURNAL OF THE KOREAN PHYSICAL SOCIETY, 56, 969-972 (2010).
Simulation results for head-on collisions of equal-sized spherical polymer nanodroplets, which were obtained by using molecular dynamics, are presented. The elastic behavior of an initial compressed phase for the colliding droplets is analyzed. Deformations and contact radii of the nanodroplets are compared with the Hertzian model of elastic solid balls. At least the initial phase of the collision could be explained by this continuum model, except at the very beginning of the collision.
