Static and Dynamic Mechanical Properties and Ballistic Behavior of 6061 Aluminum Alloy

Gaoya wuli xuebao
Aluminum alloys are widely used in aerospace, shipbuilding and high-tech fields due to their excellent mechanical properties. However, they often suffer dynamic impact loading during service.

The impact of the coupling relationship between projectile size and yarn dimension on the ballistic performance of plain weave fabric

Defence Technology
Aramid fibers, due to their relatively high inter-yarn friction, high strength, high modulus, and other characteristics, have become a typical representative of flexible anti-ballistic materials in modern warfare. Current research on the anti-penetration

Material Tests and Mesoscale Computer Model for Ballistic Impact on Carbon Fiber Composite

EPJ Web of Conferences, 2018
Two-dimensional (unidirectional) and 3-D woven carbon fiber reinforced plastic (CFRP) panels were produced by Albany Engineered Composites. Coupons were machined from the laminates for various mechanical tests in tension, torsion, and delamination.

Propagation of thermal excitations in a cluster of vortices in superfluid 3He-B

, 2011
We describe the first measurement on Andreev scattering of thermal excitations from a vortex configuration with known density, spatial extent, and orientations in 3He-B superfluid.

Effect of Grain Boundaries on Thermal Transport in Graphene

, 2012
We investigate the influence of grain boundaries (GBs), line defects (LDs), and chirality on thermal transport in graphene using non-equilibrium Green's functions.

The Bullet Cluster is not a Cosmological Anomaly

, 2015
The Bullet Cluster (1E0657-56) merger is of exceptional interest for testing the standard cold-dark-matter plus cosmological constant cosmological model, and for investigating the possible existence of a long- or short-range "fifth-force" in the dark ...

Ballistic Impact Experiments and Modelling of Sandwich Armor for Numerical Simulations

, 2014
In this paper some experimental results of a bullet impact on composite armor are discussed together with numerical modeling approaches. The development of high-quality composite sandwiches for ballistic protection is the target of a grant project in ...

Photocarrier extraction in GaAsSb/GaAsN type-II QW superlattice solar cells

, 2018
Photocarrier transport and extraction in GaAsSb/GaAsN type-II quantum well superlattices are investigated by means of inelastic quantum transport calculations based on the non-equilibrium Green's function formalism.

Perforation of welded aluminum extrusions

EPJ Web of Conferences, 2015
A purely numerical procedure for predicting the perforation resistance of welded extruded AA6082-T6 aluminum profiles is presented in this study. The numerical work was conducted completely independent of the experimental tests that were only used for ...
