TL;DR: Inelastic and charge exchange scattering of light projectiles by a nucleus is considered in this paper, where it is shown that this contribution changes only slightly the angular distribution, but may increase the cross-section strength up to a factor 4, and other processes similar to the transfer of two particles should be included in order to estimate the magnitude of all the exchange effects.

TL;DR: In this article, a hyperbolic yield criterion and Murnaghan equation of state were introduced to describe the plastic behavior of concrete material under projectile penetration, and an extended dynamic cavity expansion model was proposed.

TL;DR: In this paper , a composite double-arrow auxetic structure was designed and fabricated and the ballistic impact experiments were conducted using one stage gas gun to study the effects of the relative density on the impact responses and failure mechanism.
Abstract: A novel composite double-arrow auxetic structure was designed and fabricated in this paper. The ballistic impact experiments were conducted using one stage gas gun to study the effects of the relative density on the impact responses and failure mechanism. The impact process of the projectile was recorded by a high-speed camera. The ballistic limit velocities, damage area and failure mechanism of composite double-arrow auxetic structure with different relative densities were compared and analyzed. The anti-penetration performances of composite double-arrow auxetic structure were evaluated and discussed based on the experimental results. In order to simulate and reveal the damage evolution process, the finite element model was used to simulate the ballistic impact process of composite double-arrow auxetic structure. The ballistic limit velocities and failure modes of the simulation results were compared with that of the experimental results. The comparison indicated that the simulated results were in agreement with the experimental results.

TL;DR: In this paper, the collision of energetic ions and graphene fragments is studied in the framework of real-space finite-difference time-dependent density functional theory (TDDFT) coupled with classical molecular dynamics for nuclei.
Abstract: The collision of energetic ions and graphene fragments is studied in the framework of real-space finite-difference time-dependent density functional theory (TDDFT) coupled with classical molecular dynamics for nuclei. The amount of energy transferred from the projectile to the target is calculated to explore the defect formation mechanisms as a function of the projectile's energy. It is found that creation of defects in graphene due to the interaction of a fast proton with valence electrons is unlikely. In the case of projectiles with higher charges, the transferred energy increases significantly, leading to higher probability of bond breaking.
