Research Area 1: Material Properties and Failure

Research Area 1 of the Materials Science in Extreme Environments University Research Alliance (MSEE URA) focuses on Material Properties and Failure.

In Research Area 1, the MSEE URA will quantify materials properties and failure and their associated uncertainties in conditions relevant to weapons of mass destruction (WMD) attacks using advanced experiments and models.

This research is supported by the focus areas outlined below.

  • Focus Area 1: Material Properties for Reducing Uncertainty – First principles (FP) modeling is used to investigate equations of state (EOS) and optical, transport, and kinetic properties of matter in warm dense regimes, laser ramp compression experiments, and UQ. Initial materials of interest will be minerals present in the impact studies in Focus Area 2, Materials Constitutive Models.
  • Focus Area 2: Materials Constitutive Models – Develop and validate constitutive models for the deformation, flow, and thermal response of geomaterials subjected to dynamic compression and penetration. This effort includes identifying canonical materials and constitutive models, developing and employing advanced in situ diagnostics, applying UQ to update materials and models, and demonstrating a constitutive model prediction/validation loop.
  • Focus Area 3: Materials Properties of Energetic Materials (EM) and Additively Manufactured Energetics Materials (AMEM) – Additively fabricate model EMs with variations and gradients in their chemistries, porosity, particle size, and mechanical/thermal properties, and subject these materials to high-rate impact and thermal loadings with a suite of in situ diagnostics.
