Week 10 Bullet penetrating a Bucket Challenge
Week 10 Bullet penetrating a Bucket Challenge
AIM
To run the Explicit dynamics analysis for Mechanism Bullet penetrating a Bucket on a total of 3 different cases with change in material condition terms and provide the inference on the output.
Objective
To find and compare the results of Equivalent stress, directional deformation, Equivalent elastic strain in all cases.
For this challenge, you will have to simulate a bullet penetrating into a bucket. You will need to use 3 different non linear materials for the bucket and analyse their behaviour for the same velocity of bullet. Apply the conditions for bullet as mentioned in the video itself. Upload animation files to show the behaviour in the three cases.
CASE 1 ALUMINUM ALLOY NL
CASE 2 copper alloy nl
CASE 3 magnessium alloy nl
For all 3 case use non linear materials for the bucket and material for bullet is tantalum
CASE 1 ALUMINUM ALLOY NL
Import the model.
