Week 10 Bullet penetrating a Bucket Challenge
Bullet penetrating a bucket
Objective:
to perform a stimulation using ANSYS workbench for a bullet penetrating a bucket and also to determine total deformation and equivalent stress and other behaviors.
Procedure:
in order to start first we need to assign material for the component, the materials are going to be 3 different non-linear material for the bucket. and for the bullet we going to use tantalum material.
now we need to import the geometry in mechanical module the contact is automatically fixed and the bullet is provided with the rigid condition now we need to create a mesh using body sizing method by giving element size as 6mm.
we need to provide a fixed support for the component in order not to move during the penetration of the bullet.
The bullet is provided with the velocity of 139000 in the negative X direction.
Results:
Case 1 - For Aluminium alloy NL
Total deformation
Equivalent stress
Equivalent strain
Case 2 - For stainless steel NL
Total deformation
Equivalent stress

Case 3 - For Magnesium alloy NL
Total deformation
