High-velocity impact of titanium projectile on the aluminum plate Abaqus

Product Overview

In this example, we intend to simulate the high-velocity impact of a titanium projectile on an aluminum plate using the Abaqus software.

Materials

In this problem, the plate is made of 2618 Aluminum alloy, while the projectile is made of Ti-6Al-4V Titanium alloy.

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 titanium projectile impacts the aluminum plate at high velocity. The effect of the projectile impact on the aluminum plate is investigated using Abaqus.

Comparison with Experimental Results

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

As a result of the impact, a dent is created at the impact location on the aluminum plate.

Projectile Velocity

The velocity of the projectile is also obtained from the Abaqus analysis and its velocity diagram is plotted.

Validation

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

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