Ballistic response and failure mechanisms of gradient structured Mg alloy
Journal of Materials Research and Technology, 2023 Due to their low density, high specific damping capacity and high shock absorbency, magnesium (Mg) alloys have great potential for development as high-performance lightweight armor materials in industrial applications.

Rubber Impact on 3D Textile Composites [PDF]
, 2011 A low velocity impact study of aircraft tire rubber on 3D textile-reinforced composite plates was performed experimentally and numerically. In contrast to regular unidirectional composite laminates, no delaminations occur in such a 3D textile composite ...

SIMULATION OF BALLISTIC IMPACT ON POLYMER MATRIX COMPOSITE PANELS
Journal of Theoretical and Applied Mechanics, 2015 Composite panels, for example fuselage skins or wing skins of military aircraft, may be subjected to a variety of ballistic impacts. It is meaningful to understand the mechanical response, damage evolution and residual velocity of a projectile for panels under ballistic impact.

Simulation-Based Assessment of Rear Effect to Ballistic Helmet Impact [PDF]
Computer-Aided Design and Applications, 2010 AbstractBallistic impact is one of the major causes for traumatic brain injury (TBI) and ballistic helmets are designed to provide protection from TBI. In real life, it is impossible to use real human subjects for experiments. Therefore, simulation based-methods are convenient to assess the rear effect to ballistic helmet impact and can provide crucial

Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Advanced Materials, EarlyView.Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

NEGF simulations of a junctionless Si gate-all-around nanowire transistor with discrete dopants [PDF]
, 2012 We have carried out 3D Non-Equilibrium Green Function simulations of ajunctionlessgate-all-around n-type silicon nanowiretransistor of 4.2 × 4.2 nm2 cross-section. We model the dopants in a fully atomistic way.
