Implementation of a Realistic Damage Model in a Simulated Environment [PDF]
Problemy Mechatroniki, 2019 Realism is an important aspect of the virtual shooting range, which increases the quality of the shooting training conducted there. An important element of realism is the modeling of damage arising during the impact of the projectile on the target.

Numerical simulation of projectile penetration into steel plate based on material point method
Zhongguo Jianchuan Yanjiu, 2018 [Objectives] The FE method cannot accurately simulate crevasse patterns and the crevasse forming process when dealing with a projectile penetrating into a ship's plate because of mesh distortion.

Optics Express, 2022 Accelerating beams, of which the Airy beam is an important representative, are characterized by intensity maxima that propagate along curved trajectories. In this work we present a simple approach to directly generate accelerating beams with controllable trajectories by means of binary phase structures that consist of only a π phase step modulation in ...

A Mathematical Modeling Approach of Target Damage Strategy on the Intersection Confrontation
Mathematics, 2022 The efficiency of target damage is to measure the effect of projectile attacks. Because there is antagonism at the intersection of projectiles and targets, it is very difficult to establish scientific damage assessment strategy model and a numerical ...

Structured quantum projectiles [PDF]
Physical Review A, 2019 Matter wave interferometry is becoming an increasingly important technique in quantum metrology. However, unlike its photonic counterpart, this technique relies on the interference of particles possessing a non-zero rest mass and an electric charge. Matter waves, thus, can experience alterations in their wave-like features while propagating through ...
