Compressibility of elastomers under shock loading conditions

Dr. Pedro Peralta, a Professor for the School of Mechanical and Aerospace Engineering of the Ira A. Fulton Schools of Engineering has a research opening for the following project:

Material behavior at large pressures and strain rates plays a key role on performance of a wide range of armor and other protection systems. Elastometer coatings have shown significant potential to mitigate damage due to blast and ballistic impacts, which pose a significant threat to military, law enforcement and homeland security personnel and vehicles. However, mechanisms controlling dynamic behavior of these coatings, at pressures and strain rates typical of shock loading are not well understood. In this project thin elastomer samples will be dynamically loaded via a flyer plate impact at high velocity, and their response monitored via laser velocimetry techniques. The data, in turn, needs to be evaluated to obtain information on the equation of state of the elastomer to characterize its response to pressure under high strain rates. Techniques involved include high precision sample preparation, shock loading testing, laser velocimetry, and dynamic testing data analysis, among other. Training will be provided.

Sub-Themes:

  • Armor
  • Polymer coatings
  • Shock testing
