Week 10 Bullet penetrating a Bucket Challenge

Objective : To simulate a bullet penetrating a bucket in Ansys Workbench using explicit analysis.

Model :

Procedure:

1. Firstly changed the material of the bucket as well as the bullet.
2. Fix the bucket and give a velocity to the bullet of 139m/s.
3. Mesh the model.
4. Analysis should run for 0.01 seconds.

Mesh : Default mesh and

1. Edge sizing with 6mm mesh for the edge where the bullet is going to penetrate the bucket.

Meshed model:

The study is conducted for three different materials namely

1. Aluminum
2. Iron
3. Copper

Von mises equivalent stress:

Tabulated results:

Material	Aluminum	Copper	Iron
Max Directional Deformation(mm)	1508.7	317.18	1257.3
Max Equivalent stress(MPa)	141.82	450	427.89

Conclusion:

We found that Aluminum was the one that deformed the most , second was Iron and lastly Copper. This shows that Aluminum wont resist the bullet at all as the stress generated in bucket is least among the three. On the other hand Copper resisted the most an deformed the least.
