BULLET PENETRATING BUCKET USING EXPLICIT DYNAMICS

TITLE: BULLET PENETRATING A BUCKET

OBJECTIVE: To perform an analysis on a bucket penetrating bullet.

• In this simulation 3 different kinds of non-linear materails are used to observe the results.
• At first model is imported in space claim and cheked for error.

• Then I look for the mesh of the model.

• Then I difine the analysis setting and boundary conditions for the simulation.

• Fixing the bucket and adding some velocity to bullet.
• Now I request for results.

CASE 1: ALUMINIUM ALLOY NON-LINEAR

CASE 2: COPPER ALLOY NON-LINEAR

CASE 3: STAINLESS STEEL NON-LINEAR

RESULTS: TOTAL DEFORMATION EQUIVALENT STRESS

ALUMINIUM ALLOY NL 1390 mm 2207.6 MPa

COPPER ALLOY NL 1390 mm 2815.9 MPa

STAINLESS STEEL NL 1390 mm 1996.9 MPa

CONCLUSION: All the 3 materials have similar total deformation.Maximum stress is genrated at copper alloy non linear materal.
