Phase-dependent behavior of porous materials subjected to high strain-rate loading
Abstract
This Young Investigator Program project focuses on characterization of the dynamic behavior of inorganic multiphase porous media at high strain-rate loading in extreme environments including cryogenic temperatures. Expected knowledge is relevant for understanding multiphase material behavior involving dynamic processes related to U.S. Air Force applications including geological, astrophysical, and energetic materials systems. The overall objectives of this project are (1) characterization of the interactions within multiphase porous media, and (2) elucidation the interplays between inorganic particles in contact with water and ice at high strain-rate loading conditions. To accomplish these objectives, the proposed approach includes a balanced combination of mesoscale experiments and a Smoothed Particle Hydrodynamics-integrated Lagrangian method to reveal the dynamic behavior of porous materials. Phase-dependent dynamic behavior of porous materials requires an in-depth understanding of the dynamic equation of state (Hugoniot EoS) and its relationship with initial state parameters in addition to the interactions between particles with a phase other than solid (i.e., ice and water). The outcomes of this project will provide the essential information to characterize the Hugoniot EoS for establishing links between mesoscale and macroscale shock behavior of multiphase materials while revealing the controlling mechanisms of wave absorption and propagation characteristics in multiphase porous media.
