Additively manufactured (AM) ceramic materials provide an unprecedented level of control over specimen geometry superior to the conventional subtractive counterpart. The byproduct of this method includes defects in material geometry such as a high degree of porosity and larger grain sizes. Currently, there is…
Characterizing the ejecta generated from projectile penetration events is essential in defense and planetary sciences applications. For example, understanding the behavior of the debris cloud during missile strikes can help us minimize collateral damage. Studying the ejecta generated from both man-made and natural impacts…
The use of machine learning (ML) to guide materials search can lead to order of magnitude acceleration in finding new best-in class materials. Many steps are necessary for such ML-guided approaches to be successful and trustworthy. In this talk we focus on two specific…
The failure mechanism in porous rocks is of interest to geomechanics, defense, and planetary science applications. In this poster, we discuss ongoing work investigating the influence of water saturation on the mechanical properties and failure mechanics of sandstone. Previous studies have shown that the…
Eutectic high entropy alloy (EHEA) AlCoCrFeNi2.1, additively manufactured through laser powder bed fusion, has both high strength and ductility due to its far-from-equilibrium, dual-phase nanolamellar structure consisting of both fcc and bcc phases [1]. Understanding high pressure behavior of EHEAs is essential both for…
Machine-Learning Interatomic Potentials (MLIPs) trained on large collections of first principles calculations are rapidly becoming essential tools in the fields of computational materials science and chemistry for performing atomic-scale simulations. Despite this, apart from a few notable exceptions, there is a distinct lack of…
Recent data from heavy weapon training environments suggests that protecting the Warfighter from impulse noise exceeding 140 dB may require assessing and mitigating various modes of noise propagation into the head, rather than solely focusing on protecting air conduction through the ear canal. To…
Structural batteries are multifunctional materials capable of both storing electrical energy and providing structural rigidity. As such, structural batteries have the potential to enhance the efficiency of electrical vehicles by integrating the electrical and structural systems, thereby reducing vehicle weight, and potentially volume. The…
Shock compression of granular materials features prominently in manufacturing, defense, and planetary sciences. A significant amount of the total energy used to shock-compress powders is consumed in plasticity-induced pore collapse (Meyers 1999) followed by deformation of the grains. In this work, X-ray phase contrast…
In this study, the blast response of hybrid-fibre engineered cementitious composite (HFECC) panels is experimentally and numerically evaluated. For blast testing, HFECC and normal reinforced concrete (NRC) panels were tested under contact explosions generated by Plastic Explosive 4 (PE4) on a demolition range. The…
