Objective: To simulate and analyze a standard 0.45 pistol bullet's performance using Finite Element Analysis (FEA) in ANSYS.

Goals:

1. Evaluate bullet penetration ability against different armors.

2. Assess aerodynamic stability in various mediums (e.g., air, water).

Rationale: Address the challenges in real-life testing of high-speed projectiles and armor, which are difficult and expensive to observe due to their destructive and short-lived nature.

Methodology:

1. Utilized Explicit Dynamics and Fluent analysis modules in ANSYS.

2. Conducted explicit dynamic analysis for armor penetration tests.

3. Performed Computational Fluid Dynamics (CFD) analysis for aerodynamic stability.

Procedures:

1. Created 2D models of the bullet and steel plates.

2. Assigned materials and set up simulation parameters.

3. Analyzed bullet's velocity and pressure distributions in air and water.

Findings:

1. The bullet could penetrate a 1mm steel plate but not a stack of three such plates.

2. Lead core was crucial for enhancing penetration capability.

Aerodynamics:

1. Bullet maintained muzzle velocity in air but faced significant velocity reduction in water due to high drag forces.

Implications: Provided valuable insights into bullet and armor design, demonstrating the benefits of simulation-based testing in high-speed impact scenarios.
