Structure-Property Relationships at the Extremes: Shock Compression of Condensed Matter

Abstract:

The inelastic response and residual mechanical properties acquired from most shock compressed solids are quite different from those acquired from quasi-static or moderate strain rates. For instance, the residual hardness of many shock compressed metals has been found to be considerably lower than those loaded under quasi-static conditions to the same maximum stress. However, the residual hardness of shock compressed metals is much higher than those loaded quasi-statically to the same total strain. These observations suggest that the deformation mechanisms active during inelastic deformation under shock compression and quasi-static or moderate rates may be quite different. Therefore, the primary objective of this talk is to offer the audience a concise background on the structure-property relationships concerning shock loaded condensed matter via in-situ, end-state (recovery), and real-time X-ray diffraction shock experiments. Then elucidate the results derived from such experiments to develop a fundamental understanding of the residual mechanical properties, microstructure changes, and spall failure mechanisms in shock loaded materials with different crystal lattice structures such as 1100-O aluminum (fcc), AZ31B-H24 magnesium (hcp), fine grained AMX602 magnesium (hcp) nanocrystalline Copper-tantalum (fcc), and titanium diboride (hexagonal).

Seeing the Light: How the Mars 2020 Radiometer Optics Influenced Perceived Signal Loss

Abstract:

The Mars 2020 vehicle, carrying the Perseverance Rover and Ingenuity Helicopter, successfully landed on the Red Planet on February 18, 2021.  During its entry into the Martian atmosphere, an onboard sensor suite, dubbed MEDLI2, recorded an unprecedented number of surface pressures, in-depth temperatures, and total and radiative heat flux measurements in order to help NASA engineers reconstruct the aerothermodynamic environment surrounding the vehicle and provide a wealth of data for validating their numerical simulation tools.  In this talk, I will describe recent modeling of the on-board radiometer which improves our understanding of the radiation measurements from MEDLI2.  In particular, I will discuss how we constructed an optical model of the radiometer based on first principles, what insight the model provides for understanding the radiometer signal loss observed during flight, and how we can improve our calibration procedures in the future.

From a tiny spark to a massive explosion --  modeling the multi-scale physics of detonations of solids

Abstract: Multi-scale modeling of energetic materials (propellants, explosives, and pyrotechnics) and their sensitivity requires telescoping physics from the nano- and micro- and meso-scales in order to make predictions of their macro-scale response. While atomistic simulations must inform meso-scale models, meso-scale models must provide closure to macro-scale simulations. This talk will highlight the physics at various scales that play a role in the cascade of events that leads from a tiny spark to a massive explosion. In particular, we focus on detonations in condensed phase energetic materials which are typically composites comprised of organic crystals, binders and additives (metals, plasticizers, etc). The state-of-the-art understanding of the physics and modeling of the multi-scale phenomena will be highlighted with special emphasis on the emerging multifarious roles of artificial intelligence in simulation and design of solid composite energetic materials.

A technical ecosystem to enable multi-messenger astrophysics

Abstract:
With the detection of compact binary coalescences and their electromagnetic counterparts by gravitational-wave detectors, a new era of multi-messenger astronomy has begun. In this talk, I will describe how current ground based optical surveys and dedicated follow-up systems are being used to identify more of these, and how we are developing models to test what we find. I will further describe the variety of technical challenges we currently face and ideas for what we might learn from optimization techniques more common in the aerospace field. We will close with near-term prospects for the field.

Bio: 

My research focuses on using multi-messenger astronomy to study the Universe, coming at the same problem from multiple directions to gain a more complete picture. In particular, I study the coalescence of binary neutron stars with both gravitational waves and electromagnetic data, predominantly using wide field-of-view optical telescopes such as the Zwicky Transient Facility (ZTF) to identify these counterparts. I also use these telescopes to search for future sources from the Laser Interferometer Space Antenna (LISA), a space-based gravitational wave detector that will study white dwarf binaries in our galaxy as well as binary black hole mergers.
