Animated sequence of snapshots from a MD simulation of an explosive disintegration of a matrix-polymer droplet

Animated GIF Image
Fast heating (partial stress confinement), deposited energy is 0.63 Ec

This animation shows an explosive disintegration of a 60 nm droplet containing 16 wt.% of randomly oriented polymer chains. The droplet is heated during the first 100 ps of the simulation, with the total amount of the deposited thermal energy equal to 63% of the cohesive energy of the matrix material. The heating rate corresponds to the partial inertial stress confinement - the conditions under which compressive stresses build up during the heating process and contribute to the droplet disintegration.

Matrix molecules and units of polymer chains are shown by black and blue dots, respectively. Polymer molecules in the front half of the computational cell are superimposed on top of the matrix molecules.
