In this work, a numerical model for aramid composites is experimentally validated in terms of permanent deformation, energy absorption and damage mechanisms ballistic applications. Novel experimental results non-perforating impacts with blunt projectiles are presented. The resistance forces by the specimen measured different impact velocities. A postmortem analysis failure performed using compu...

Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance-a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of bands crossing the Fermi energy when the magnetizati...

Elastic-recoil mechanisms can improve organismal performance and circumvent the thermal limitations of muscle contraction, yet they require the appropriate motor control to operate. We compare muscle activity during tongue projection in salamanders with elastically powered, ballistic projection with activity of those with muscle-powered, non-ballistic projection across a range of temperatures t...

Abstract A representative and most commonly used ballistic target system consisting of a 93W ball Q235 steel plate is investigated for its limit fast calculation engineering model. The basic data on the material projectile was obtained through quasi-static compression tests mechanical properties materials. Using Φ12.7mm gun ten shot v50 method, were carried out with balls positively penetrating...

In Phys. Rev. Lett. 120, 200603 (2018), a segmented XXZ spin chain with zero anisotropy in one half and large on the other gave rise to current rectification which is perfect thermodynamic limit. Here we extend previous study chains interacting integrable as well non-integrable halves, considering even cases no ballistic transport can emerge either half. We demonstrate that, also this more gene...

Abstract. The Boltzmann–Poisson system modeling the electron flow in semiconductors is used to discuss the validity of the Child–Langmuir asymptotics. The scattering kernel is approximated by a simple relaxation time operator. The Child–Langmuir limit gives an approximation of the currentvoltage characteristic curves by means of a scaling procedure in which the ballistic velocity is much larger...

We give a general existence result for interacting particle systems with local interactions and bounded jump rates but noncompact state space at each site. We allow for jump events at a site that affect the state of its neighbours. We give a law of large numbers and functional central limit theorem for additive set functions taken over an increasing family of subcubes of Zd. We discuss applicat...

We study the behavior of two-dimensional Dirac fermions in the presence of a static long-range-correlated random vector potential. By applying an exact path integral representation for the propagator of a spinor particle we obtain asymptotics of the gauge invariant spectral function and the correlation function of the local density of states, both in the ballistic regime of sufficiently high en...
