Penetration of a projectile into an aluminum plate Abaqus

Product Overview

In this example, we intend to simulate the penetration of a projectile into an aluminum plate using the Abaqus software.

Model Description

In this problem, the rigid projectile impacts the AA5083-H116 Aluminum plate at a high velocity. Due to the high impact velocity, the projectile penetrates the aluminum plate.

Johnson-Cook Damage Model

To accurately simulate the material failure during the high-velocity impact, the Johnson-Cook damage model is used in Abaqus. This model is suitable for describing the failure behavior of ductile metals under conditions involving large plastic deformation, high strain rates, and material failure.

In this simulation, the Johnson-Cook damage model is used to predict the initiation and evolution of damage in the material during the impact process. The model considers the effects of plastic strain, strain rate, and temperature on material failure.

Effect of Temperature

In this analysis, the effect of temperature on the deformation of the Aluminum plate is considered. The required thermal properties of Aluminum are defined in the Abaqus software to account for the temperature effect during the penetration process.

Different Projectile Velocities

The problem is solved for different projectile velocities. The analysis is repeated several times, and the initial velocity of the projectile is changed for each simulation.

Residual Velocity

The residual velocity (final velocity) of the projectile is obtained from the Abaqus results. A diagram of the residual velocity is plotted based on the striking velocity (initial velocity) of the projectile.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the reference article.

In other words, this project is based on the reference research article.
