“…The ballistic performance of the monolithic target was better at higher velocities than in contact-type target plates. 18 The authors Ranaweera et al 19 also confirmed fact that three-layered metal plates are poorly understood, and developing this topic, and investigated a targets composed of steel, titanium and aluminum layers impacted by non-rigid NATO FMJ M80 projectiles. Some penetration and perforation problems, including perforation metal targets with elongated rods were numerically solved in Kraus et al 20 The good correlation in terms the self-similar modeling Zlatin’s curve in dimensionless coordinates L/H (crater depth to the striker length) and E/Y (kinetic energy to the yield point) was obtained.…”

The results of numerical simulation of perforation of monolithic and multi-layered targets are presented. The objects of study were monolithic, two-layer, three-layer and air gap targets made of steel 3. The influence of the placement of an additional layer on impact resistance in high-velocity impact (initial velocity was more than the ballistic limit of all targets) was investigated. The behavior of materials was described using a phenomenological macroscopic model of continuum mechanics. A modified Lagrangian method was used for numerical simulation of the perforation process. Test calculations were performed before numerical research. Good agreement on penetration depth of an ogival striker into a semi-infinite metal target was obtained. Numerical simulation found that impact resistance of the triple-layered target was higher than that of the double-layered target and monolithic targets. Post-perforation analysis showed the targets were completely perforated and the striker’s tip was slightly eroded or blunted. Duration of perforation of all targets and damage to their materials were approximately the same, but permanent deformation of additional layers was greater with a triple-layered target. This finding can be explained by a pinching effect of additional layers acting on the striker and decelerating it.

“…A summary of seminal experimental impact results and discussions of basic penetration mechanisms is given in [1,2]. These studies characterize a number of plate impact perforation mechanisms as (1) fracture due to stress waves [3][4][5][6][7], (2) radial fracture behind a stress wave [5,[8][9][10][11], (3) spallation [9,[12][13][14][15][16][17], (4) shear plugging [13,[18][19][20][21][22][23][24][25], (5) petaling [19,[26][27][28][29][30][31][32], (6) fragmentation [9,[33][34][35][36][37][38], and (7) ductile-hole enlargement [39][40][41]…”

An internal state variable (ISV)-based constitutive model has been used within a Lagrangian finite element analysis (FEA) framework to simulate ballistic impact of monolithic rolled homogenous armor (RHA) steel plates by RHA steel spheres and cylinders. The ISV model predictions demonstrate good agreement with experimental impact data for spherical projectiles. A simulation-based parametric sensitivity study was performed to determine the influence of a variety of microstructural and mechanical properties on ballistic performance. The sensitivity analysis shows that the lattice hydrogen concentration, material hardness, and initial void volume fraction are dominant factors influencing ballistic performance. Finite element simulations show that variation of microstructure properties could explain the reduced ballistic performance of high hardness materials previously documented in the literature. The FEA framework presented in this work can be used to determine material properties conducive to ballistic-impact resistance.
