Energy-Balance Checklist
A checklist for verifying the energy balance in an explicit impact analysis.
Checklist
- Total energy is approximately constant
- Internal energy increases as target deforms
- Kinetic energy decreases as projectile slows
- Hourglass energy is less than 5-10% of internal energy
- Deleted energy is accounted for
- Contact energy is small relative to internal energy
- No unexplained energy generation or loss
