1. What is Effective Armor Thickness?

Effective armor thickness is the actual thickness of armor that a projectile must penetrate when striking at an angle, taking into account the angle of impact. It's a crucial concept in armor penetration calculations.

2. How Does the Calculator Work?

The calculator uses the effective thickness formula:

Where:

• \( Thickness \) — Actual thickness of the armor plate (mm)
• \( angle \) — Angle of impact from perpendicular (degrees)

Explanation: The formula accounts for the increased path length through the armor when striking at an angle.

3. Importance of Effective Thickness Calculation

Details: Understanding effective thickness is essential for evaluating armor protection, comparing different armor designs, and calculating penetration requirements.

4. Using the Calculator

Tips: Enter armor thickness in millimeters and impact angle in degrees (0-89.9). The angle should be measured from perpendicular to the armor surface.

5. Frequently Asked Questions (FAQ)

Q1: Why does angle affect armor effectiveness?
A: At an angle, the projectile must travel through more material to penetrate, effectively increasing the armor's resistance.

Q2: What's the maximum angle this works for?
A: The formula works best for angles below 70°. At very high angles, other factors like ricochet become important.

Q3: Does this account for armor quality?
A: No, this only calculates geometric effectiveness. Actual protection depends on armor material and construction.

Q4: How does this relate to tank armor design?
A: Sloped armor uses this principle to achieve greater protection without increasing weight.

Q5: Are there limitations to this calculation?
A: Yes, it doesn't account for projectile shape, armor material properties, or the possibility of ricochet.
