Rubbers are effective materials for mitigating shock waves and high-velocity impacts. Despite their potential benefits in these extreme applications, relatively few studies have rigorously investigated the penetration behavior of rubbers or their shock Hugoniots. Here, we present experiments that quantify the ability of a…
Ultra-High Molecular Weight Polyethylene (UHMWPE) fiber-reinforced composites are used as protective materials against ballistic impact due to their impressive properties such as their high strength and low weight characteristics. This work investigates the dynamic behavior of UHMWPE fiber-reinforced composite under ballistic and plate impact…
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…
