“…Some existing work on oblique impact [17][18][19][20][21][22][23] or near normal impact of the yawed projectiles [24][25][26][27][28][29][30][31] should also be noted. Although some useful information about the behaviour of the projectile and target during high-velocity impact can be obtained from these studies, they are focused more on the penetration and perforation process rather than the ricochet phenomena and, in particular, critical ricochet conditions.…”

“…The mass of the projectile varied from 15 to 100 g. They observed that the ballistic limit of the plate changes with projectile mass and nose shape. Goldsmith et al [6] experimentally investigated normal impact of cylindro-conical and blunt projectiles into aluminum and steel sheet targets. The thickness of aluminum targets varied from 1.78 mm to 25.4 mm and that of steel plates varies from 1 mm to 19 mm.…”

In this paper an experimental and numerical work is reported concerning the process of perforation of thin steel plates using different projectile nose shapes. The main goal is to analyze how the projectile shape may change the ballistic properties of materials. A wide range of impact velocities from 35 to 180 m/s has been covered during the tests. All the projectiles were 13mm in diameter and the targets were 1mm thick, as such the projectile can be regarded as rigid and the target sheets were of interstitial-free (IF) steel. The mass ratio (projectile mass/steel sheet mass) and the ratio between the span of the steel sheet and the diameter of the projectile were kept constant, equal to 0.38 and 3.85 respectively. To define the thermoviscoplastic behaviour of the target material, the Rusinek-Klepaczko (RK) constitutive model [1] was used. The complete identification of the material constants was done based on a rigorous material characterization. Numerical simulations of some experimental tests were carried out using a non-linear finite element code ABAQUS/Explicit. It was found that the numerical models are able to describe the physical mechanisms in the perforation process with a good accuracy.

“…When a flat metallic thin film is impacted by a hard indenter, it typically undergoes radial cracking (RC) [33][34][35].

In lithium-ion battery (LIB), mechanical abuse often leads to internal short circuits (ISC) that trigger thermal runaway. We investigated a thermal-runaway mitigation (TRM) technique using modified current collector. By generating surface grooves on the current collector, the area of electrodes directly involved in ISC could be largely reduced, which decreased the ISC current. The TRM mechanism took effect immediately after the LIB was damaged. The testing data indicate that the groove width is a critical factor. With optimized groove width, this technique may enable robust and multifunctional design of LIB cells for large-scale energy-storage units.
