Impact of a blunt-nosed projectile with an Aluminum plate (1100-H12) in the Abaqus

Product Overview

In this example, we intend to simulate the impact of a blunt-nosed projectile with an Aluminum plate using the Abaqus software.

Model Description

In this problem, the blunt-nosed projectile is modeled as a rigid body, while the target plate is made of 1100-H12 Aluminum.

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.

Impact Analysis

In this analysis, the blunt-nosed projectile impacts the Aluminum plate. The deformation and impact behavior of the Aluminum plate are investigated using Abaqus.

Deformation

The deformation obtained from the Abaqus software is compared with the experimental results. As can be observed, the numerical results are very similar to the experimental results.

Residual Velocity

The residual velocity of the projectile is obtained from the Abaqus analysis. A diagram of the residual velocity based on the initial velocity is plotted.

Validation

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

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