Week 10 Bullet penetrating a Bucket Challenge

Objective: To simulate a bullet (TANTALUM) penetrating a bucket using explicit dynamics module of ANSYS Workbench for three different materials of bucket.

1. Case 1: AL 1100-O
2. Case 2: IRON
3. Case 3: STEEL 1006

Procedure:

1. Contacts: Since it is a highly dynamic event, no contacts are defined.
2. Body Interactions:
   
   1. Type: Frictionless.
   2. Other Settings: Default.
3. Meshing:
4. Boundary Conditions:

Analysis:

1. Case 1:
   1. Total Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Plastic Strain:
   4. Equivalent Stress:
   5. Temperature:
2. Case 2:
   1. Total Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Plastic Strain:
   4. Equivalent Stress:
   5. Temperature:
3. Case 3:
   1. Total Deformation:
   2. Equivalent Elastic Strain:
   3. Equivalent Plastic Strain:
   4. Equivalent Stress:
   5. Temperature:

Result:
