P O L Y M E R S Our goal is to prevent the catastrophic failure of ballistic body armor by developing measurements and predictive models to test and determine the long-term reliability of polymers used in ballistic resistant armor. Our approach, which utilizes conventional analytical techniques in addition to newly developed minimally invasive test methods, seeks to identify the chemical and me...

A non-equilibrium molecular dynamics method is employed to study the mechanical response of soda-lime glass (a material commonly used in transparent armor applications) when subjected to the loading conditions associated with the generation and propagation of planar shock waves. Specific attention is given to the identification and characterization of various (inelastic-deformation and energy-d...

Recent technological advancements led to active research in the field of additive manufacturing (AM) thanks its ability fabricate complex structures with reduced material waste. While many studies focused on quasi-static performance AM materials and structures, investigations dynamic these are still limited, especially for polymers composites. The aim this is investigate fracture behaviour poly...

Uncertainties in certain features of target geometries result in a loss of confidence in the signature assessment of the target. Knowledge of the impact to a target’s radar cross section (RCS) due to changes to specific target features can assist to identify whether uncertainty in a certain target feature warrants a loss of confidence in the target signature. This study will allow a development...

The finding that Russia is in violation of its obligations under the Intermediate-Range Nuclear Forces Treaty has raised doubts about its durability. If the treaty cannot be revived, the United States could choose to add conventional land-based theater ballistic missiles to its arsenal. The U.S. Army should start a rigorous assessment of the potential military value and potential strategic risk...
