Mechanism of Improving Ballistic Performance of Kevlar through Impregnation of Nanoparticles,at higher treatment levels, the nanoparticles tend to agglomerate in the interstitial spaces of yarn crossover points, which helps better engage secondary yarns away from the impact location of the projectile. Inspecting the back-face damaged zone areas for penetrative cases shows a strong positive

Mixed-Mode Dynamic Fracture Behavior of Soda-Lime Glass Studied using Digital Gradient Sensing Meths intensity factor histories prior to and at crack initiation will be evaluated in the next phase by performing an over-deterministic least squares analysis on optically measured full-field data. From the critical stress intensity factors at crack initiation, a fracture envelope for SLG encompassing

Experimental Investigation of the Nonlocal Dynamic Damage Mechanism in Shale,n, is utilized to monitor the full-field strain and nonlocal damage initiation. As a result, two different dynamic damages are observed and discussed. The experimental setup and the nonlocal damage as a function of the bedding direction are also discussed.

A Study on the Influence of Concrete Saturation Ratio for Depth of Penetration Experiments, of penetration experiments were performed using CSC targets at three highly controlled saturation ratios: ambient cured, saturated, and oven-dried. The depth of penetration experiments are ideal experiments for probing the saturation effects on the concrete due to the high pressures induced by impa

Effect of Crystal Size on the Failure Mechanics of Polymer-Bonded Explosives, is applied to these samples using a split Hopkinson pressure bar (SHPB). The macroscale and local dynamic deformation of the samples are captured by taking a series of images of the samples as they deform using a high-speed camera. From the macroscale experiment, it was observed that as the crystal

High-Strain-Rate Behavior of 3D-Printed CuCrZr,for the sake of comparison. High-speed imaging has been used to capture the real strain of the specimens. The results showed a limited positive strain rate sensitivity in terms of flow stress for as-built conditions, whereas negative strain rate sensitivity was observed for the heat-treated samples,

A Vertical Ballistics Range with Photon Doppler Velocimeter Instrumentation for Projectile Penetratng flight and penetration into soil targets. Magnetic sensors were used to trigger the data acquisition system. Additional magnetic sensors were assembled to measure the projectile muzzle velocity when steel projectiles were used. Loose- and Densely-packed soil targets were prepared by means of pluv

Large Deformation Explicit Finite Element Simulations of Drop Tower Experiments on Clay,gth was observed at a strain rate of 56/s compared to the quasi-static strength. Three-dimensional finite element simulations of the drop tower setup were then used to replicate the observed response. A penalty contact algorithm, available in the commercial finite element code Abaqus/Explicit, was u
