bullet penetrating bucket simulation using explicit dynamics

Objective:- In this challenge we need to perform a bullet penetrating bucket simulation in explicit dynamic and observer the stress and deformation results values by assigining different materials to bucket .

Set-up and Pre processing done in mechanical model are as follows:-

material was assigned to the bucket and bullet and kept the bullet as a rigid body.

default connections was deleted and the body interaction is set to frictionless.

Meshing is done bu keeping the side edge sizing of 4 mm.

analysis setting is given by :-

Then boundary condition are fixed support to the bucket and the velocity applied to the bullent in x-coordinate 139000mm/sec.

In this way the pre-processing was done and in the three cases material for the bucket has been modified and stress and deformation results are carried out.

Case 1.

bucket material= aluminium 1100-o

bullet material = tantalum.

case 2

bucket material=AL 2024-T4

bullet material = tantalum

case 3

bucket material=gold 5%cu

bullet material = tantalum
