Numerical and analytical simulation of ballistic projectile penetration due to high velocity impact on ceramic target

Abstract

Simulation and analysis of the projectile impact and penetration problem and its effects are among the practical topics that can be used to design bulletproof panel and military equipment, construction of impact and penetration resistant structures, design of projectiles with appropriate penetration strength and High performance noted. One of the most important parameters affecting penetration is the impact velocity of the projectile. The mechanism of penetration varies in different speed ranges. In this paper, Ansys Autodyn software is used for intrusion simulation. The simulation carried out in this study is based on the accuracy and physical conditions of the problem and the compatibility of numerical simulation with the governing analytical relationships indicates the validity and accuracy of the assumptions made in the simulation. In this study, we selected materials such as material behavior, grating, contact surfaces, and controls, as well as collision of the blunt projectile with angles of 0º,15º,30º,45º by of high velocity impact 1000 m/s with the same mass and diameter and shape of the projectile nose and properties. Ceramic materials are discussed. The result of the numerical simulation comparison shows relatively good agreement between them.

An Efficient Analysis Method of Aluminum Alloy Helicopter Fuselage Projectile Damage Based on Projectile Breakdown Theory

“…Neural network and decision tree regression models were trained by Pushkar through finite element simulations and applied to predict the penetration analysis of projectiles on laminates [1]. Amin used FEM to compute the high-speed impact of the projectile and studied the impact damage effect characteristics of mass, diameter, warhead shape, and properties of ceramic materials [2]. Senthil and Iqbal found that monolithic aluminum targets have higher ballistic performance than double-layered in-contact targets against ogive-nosed projectiles [3].…”

Perforation Characteristics of Three-Layer Steel Plates Subjected to Impact with Different Shapes and Velocities of Reactive Fragments

“…The thin plates used in space debris protection research are mainly composed of lightweight structural materials, and their response is different from that of high-strength thin-plate materials such as steel [3][4][5][6]. Moreover, the speed of space debris is usually greater than 7 km/s, which exceeds the impact velocity possessed by projectiles under normal circumstances [7,8]. The current research focuses on hot topics with velocities ranging from 1.5 to 4.5 km/s, and most of them are spherical and cylindrical projectiles [9].…”

Ballistic Testing Simulation of Ultra-High Strength Steel Water Layer Sandwich Structure

“…High velocity perforation problems are coupled with large deformations, erosion, high strain rate dependent, nonlinear material behaviour, thermal softening and fragmentation [4]. Analytical and empirical approaches are inadequate to capture the multi-physical mechanisms involving in perforation problems which include failure, friction heating, fracture, residual stresses among others [5]. Layered composite systems with hard front faced materials such as ceramic and high strength steels when coupled with soft backing materials are mostly used to reduce perforations [2,6].…”
