Coefficient of Restitution for Viscoelastic Materials
Sangrak Kim
An analytical expression of the coefficient of restitution for viscoelastic materials is derived for the viscous-dominant case, such as collisions of polymeric melt. The recently p…
Second Blows in the Head-on Collisions of the Spherical Nano Polymer Droplets
Sangrak Kim
We report observations of weird but interesting phenomenon from the molecular dynamics simulations, occurrence of second blows in the head-on collisions of two equal-sized spherica…
A New Description of Quantum Behaviors for a Simple Harmonic Oscillator
Sangrak Kim
We describe quantum behaviors of a simple harmonic oscillator, starting from the classical mechanics. By imposing two conditions on the phase points generated from a symplectic alg…
Validity of Molecular Dynamics Simulations for Soft Matter
Sangrak Kim
In this work, we analytically examine the validity of molecular dynamics for a soft potential system by considering a simple one-dimensional system with a piecewise continuous line…
Elastic behavior of spherical nanodroplets in head-on collision
Sangrak Kim
Simulation results for head-on collisions of equal-sized spherical polymer nanodroplets using molecular dynamics are presented. Elastic behavior of an initial compressed phase for…
