Thin films form an essential part of in situ detectors used in the study of micrometeroids. With the development of sensor arrays using thin films with thickness between 500 and 1000 A an investigation of the response of the films to hypervelocity impacts was undertaken using Molecular Dynamics. A projectile of 256 particles and a film with a surface area forty‐nine times greater than the projectile are equilibriated using a Lennard‐Jones potential. The film is subdivided into forty‐nine equal volume elements whose dimensions are equal to the projectile’s initial volume. The thermodynamic response of these volume elements are used to analyze the propagation of the shockwave in the thin film as a function of impact speed, radial distance from the impact site, and the elasped time from the moment of impact. |
